Given numbers are 974, 668, 942, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(974, 668) = 325316
GCD(974, 668) = ( 974 x 668 ) / 325316
= 974 / 668
= 974
Step2:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
Step3:
LCM(2, 255) = 510
GCD(2, 255) = ( 2 x 255 ) / 510
= 2 / 255
= 2
So, Greatest Common Divisor of 974, 668, 942, 255 is 1
