Given numbers are 130, 872, 457, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 872) = 56680
GCD(130, 872) = ( 130 x 872 ) / 56680
= 130 / 872
= 130
Step2:
LCM(2, 457) = 914
GCD(2, 457) = ( 2 x 457 ) / 914
= 2 / 457
= 2
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 130, 872, 457, 921 is 1
