Given numbers are 71, 42, 15, 46
The list of prime factors of all numbers are
Prime factors of 71 are 71
Prime factors of 42 are 2 x 3 x 7
Prime factors of 15 are 3 x 5
Prime factors of 46 are 2 x 23
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 71, 42, 15, 46 using LCM Formula
Given numbers are 71, 42, 15, 46
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(71, 42) = 2982
GCD(71, 42) = ( 71 x 42 ) / 2982
= 71 / 42
= 71
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 46) = 46
GCD(1, 46) = ( 1 x 46 ) / 46
= 1 / 46
= 1
So, Greatest Common Divisor of 71, 42, 15, 46 is 1
