Given numbers are 62, 30, 61, 20
The list of prime factors of all numbers are
Prime factors of 62 are 2 x 31
Prime factors of 30 are 2 x 3 x 5
Prime factors of 61 are 61
Prime factors of 20 are 2 x 2 x 5
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 62, 30, 61, 20 using LCM Formula
Given numbers are 62, 30, 61, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(62, 30) = 930
GCD(62, 30) = ( 62 x 30 ) / 930
= 62 / 30
= 62
Step2:
LCM(2, 61) = 122
GCD(2, 61) = ( 2 x 61 ) / 122
= 2 / 61
= 2
Step3:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
So, Greatest Common Divisor of 62, 30, 61, 20 is 1
