Given numbers are 656, 380, 820, 754

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

Apply this formula for all numbers.

Step1:

LCM(656, 380) = 62320

GCD(656, 380) = ( 656 x 380 ) / 62320

= 656 / 380

= 656

Step2:

LCM(4, 820) = 820

GCD(4, 820) = ( 4 x 820 ) / 820

= 4 / 820

= 4

Step3:

LCM(4, 754) = 1508

GCD(4, 754) = ( 4 x 754 ) / 1508

= 4 / 754

= 4

So, Greatest Common Divisor of 656, 380, 820, 754 is 2
