Given numbers are 764, 508, 691, 780

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

Apply this formula for all numbers.

Step1:

LCM(764, 508) = 97028

GCD(764, 508) = ( 764 x 508 ) / 97028

= 764 / 508

= 764

Step2:

LCM(4, 691) = 2764

GCD(4, 691) = ( 4 x 691 ) / 2764

= 4 / 691

= 4

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 764, 508, 691, 780 is 1
