Given numbers are 738, 246, 847, 645

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

Apply this formula for all numbers.

Step1:

LCM(738, 246) = 738

GCD(738, 246) = ( 738 x 246 ) / 738

= 738 / 246

= 738

Step2:

LCM(246, 847) = 208362

GCD(246, 847) = ( 246 x 847 ) / 208362

= 246 / 847

= 246

Step3:

LCM(1, 645) = 645

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

= 1 / 645

= 1

So, Greatest Common Divisor of 738, 246, 847, 645 is 1
