How do you calculate GCD?

The steps to calculate the GCD of (a, b) using the LCM method is:

Step 1: Find the product of a and b.
Step 2: Find the least common multiple (LCM) of a and b.
Step 3: Divide the values obtained in Step 1 and Step 2.
Step 4: The obtained value after division is the greatest common divisor of (a, b).

What is the HCF of 166?

The biggest common factor number is the GCF number. So the greatest common factor 166 and 230 is 2.

What is the GCD of 120?

The prime factorization of 120 is 2 x 2 x 2 x 3 x 5 = 120. The occurrences of common prime factors of 20, 50 and 120 are 2 and 5. So the greatest common factor of 20, 50 and 120 is 2 x 5 = 10.

How do you manually calculate GCD?

Greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors. For example, to compute gcd(48, 180), we find the prime factorizations 48 = 24 · 31 and 180 = 22 · 32 · 51; the GCD is then 2 · 3 · 5 = 22 · 31 · 50 = 12, as shown in the Venn diagram.

What is the prime factor of 166?

The Prime Factors of 166 are 2 × 83 and its Factors in Pairs are (1, 166), (2, 83).

What are the Factors of 167?

What are the Factors of 167? The factors of 167 are 1, 167 and its negative factors are -1, -167.

What is GCF and LCM?

The greatest common factor (GCF) is the largest number that is a factor of two or more numbers, and the least common multiple (LCM) is the smallest number that is a multiple of two or more numbers. …

What is the greatest common factor of 160?

The numbers which we multiply to get 160 are the factors of 160. Factors of 160 are written as 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The number itself is a factor of the number as it divides itself exactly….Factors of 160 in Pairs.
