Given numbers are 474, 640, 24, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(474, 640) = 151680
GCD(474, 640) = ( 474 x 640 ) / 151680
= 474 / 640
= 474
Step2:
LCM(2, 24) = 24
GCD(2, 24) = ( 2 x 24 ) / 24
= 2 / 24
= 2
Step3:
LCM(2, 658) = 658
GCD(2, 658) = ( 2 x 658 ) / 658
= 2 / 658
= 2
So, Greatest Common Divisor of 474, 640, 24, 658 is 2
