Given numbers are 666, 530, 478, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 530) = 176490
GCD(666, 530) = ( 666 x 530 ) / 176490
= 666 / 530
= 666
Step2:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
Step3:
LCM(2, 917) = 1834
GCD(2, 917) = ( 2 x 917 ) / 1834
= 2 / 917
= 2
So, Greatest Common Divisor of 666, 530, 478, 917 is 1
