Given numbers are 662, 971, 246, 645

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

Apply this formula for all numbers.

Step1:

LCM(662, 971) = 642802

GCD(662, 971) = ( 662 x 971 ) / 642802

= 662 / 971

= 662

Step2:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 662, 971, 246, 645 is 1
