Given numbers are 646, 476, 740, 974

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(646, 476) = 9044

GCD(646, 476) = ( 646 x 476 ) / 9044

= 646 / 476

= 646

Step2:

LCM(34, 740) = 12580

GCD(34, 740) = ( 34 x 740 ) / 12580

= 34 / 740

= 34

Step3:

LCM(2, 974) = 974

GCD(2, 974) = ( 2 x 974 ) / 974

= 2 / 974

= 2

So, Greatest Common Divisor of 646, 476, 740, 974 is 2
