Given numbers are 639, 786, 851, 783

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

Apply this formula for all numbers.

Step1:

LCM(639, 786) = 167418

GCD(639, 786) = ( 639 x 786 ) / 167418

= 639 / 786

= 639

Step2:

LCM(3, 851) = 2553

GCD(3, 851) = ( 3 x 851 ) / 2553

= 3 / 851

= 3

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 639, 786, 851, 783 is 1
