Given numbers are 780, 428, 579, 879

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

Apply this formula for all numbers.

Step1:

LCM(780, 428) = 83460

GCD(780, 428) = ( 780 x 428 ) / 83460

= 780 / 428

= 780

Step2:

LCM(4, 579) = 2316

GCD(4, 579) = ( 4 x 579 ) / 2316

= 4 / 579

= 4

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 780, 428, 579, 879 is 1
