Given numbers are 668, 654, 427, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 654) = 218436
GCD(668, 654) = ( 668 x 654 ) / 218436
= 668 / 654
= 668
Step2:
LCM(2, 427) = 854
GCD(2, 427) = ( 2 x 427 ) / 854
= 2 / 427
= 2
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 668, 654, 427, 831 is 1
