Given numbers are 678, 390, 929, 777

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

Apply this formula for all numbers.

Step1:

LCM(678, 390) = 44070

GCD(678, 390) = ( 678 x 390 ) / 44070

= 678 / 390

= 678

Step2:

LCM(6, 929) = 5574

GCD(6, 929) = ( 6 x 929 ) / 5574

= 6 / 929

= 6

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 678, 390, 929, 777 is 1
