Given numbers are 640, 130, 218, 934
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 130) = 8320
GCD(640, 130) = ( 640 x 130 ) / 8320
= 640 / 130
= 640
Step2:
LCM(10, 218) = 1090
GCD(10, 218) = ( 10 x 218 ) / 1090
= 10 / 218
= 10
Step3:
LCM(2, 934) = 934
GCD(2, 934) = ( 2 x 934 ) / 934
= 2 / 934
= 2
So, Greatest Common Divisor of 640, 130, 218, 934 is 2
