Given numbers are 658, 530, 251, 651
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 530) = 174370
GCD(658, 530) = ( 658 x 530 ) / 174370
= 658 / 530
= 658
Step2:
LCM(2, 251) = 502
GCD(2, 251) = ( 2 x 251 ) / 502
= 2 / 251
= 2
Step3:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
So, Greatest Common Divisor of 658, 530, 251, 651 is 1
