Given numbers are 777, 639, 571, 801

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

Apply this formula for all numbers.

Step1:

LCM(777, 639) = 165501

GCD(777, 639) = ( 777 x 639 ) / 165501

= 777 / 639

= 777

Step2:

LCM(3, 571) = 1713

GCD(3, 571) = ( 3 x 571 ) / 1713

= 3 / 571

= 3

Step3:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

So, Greatest Common Divisor of 777, 639, 571, 801 is 1
