Given numbers are 777, 147, 629, 642

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

Apply this formula for all numbers.

Step1:

LCM(777, 147) = 5439

GCD(777, 147) = ( 777 x 147 ) / 5439

= 777 / 147

= 777

Step2:

LCM(21, 629) = 13209

GCD(21, 629) = ( 21 x 629 ) / 13209

= 21 / 629

= 21

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 777, 147, 629, 642 is 1
