Given numbers are 642, 412, 354, 777

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

Apply this formula for all numbers.

Step1:

LCM(642, 412) = 132252

GCD(642, 412) = ( 642 x 412 ) / 132252

= 642 / 412

= 642

Step2:

LCM(2, 354) = 354

GCD(2, 354) = ( 2 x 354 ) / 354

= 2 / 354

= 2

Step3:

LCM(2, 777) = 1554

GCD(2, 777) = ( 2 x 777 ) / 1554

= 2 / 777

= 2

So, Greatest Common Divisor of 642, 412, 354, 777 is 1
