Given numbers are 390, 678, 649, 776

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 678 are 2 x 3 x 113

Prime factors of 649 are 11 x 59

Prime factors of 776 are 2 x 2 x 2 x 97

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 390, 678, 649, 776

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

Apply this formula for all numbers.

Step1:

LCM(390, 678) = 44070

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

= 390 / 678

= 390

Step2:

LCM(6, 649) = 3894

GCD(6, 649) = ( 6 x 649 ) / 3894

= 6 / 649

= 6

Step3:

LCM(1, 776) = 776

GCD(1, 776) = ( 1 x 776 ) / 776

= 1 / 776

= 1

So, Greatest Common Divisor of 390, 678, 649, 776 is 1
