Given numbers are 51, 73, 65, 72
The list of prime factors of all numbers are
Prime factors of 51 are 3 x 17
Prime factors of 73 are 73
Prime factors of 65 are 5 x 13
Prime factors of 72 are 2 x 2 x 2 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 51, 73, 65, 72 using LCM Formula
Given numbers are 51, 73, 65, 72
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(51, 73) = 3723
GCD(51, 73) = ( 51 x 73 ) / 3723
= 51 / 73
= 51
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
So, Greatest Common Divisor of 51, 73, 65, 72 is 1
