Given numbers are 130, 451, 772, 642
The list of prime factors of all numbers are
Prime factors of 130 are 2 x 5 x 13
Prime factors of 451 are 11 x 41
Prime factors of 772 are 2 x 2 x 193
Prime factors of 642 are 2 x 3 x 107
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 130, 451, 772, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 451) = 58630
GCD(130, 451) = ( 130 x 451 ) / 58630
= 130 / 451
= 130
Step2:
LCM(1, 772) = 772
GCD(1, 772) = ( 1 x 772 ) / 772
= 1 / 772
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 130, 451, 772, 642 is 1
