Given numbers are 651, 365, 839, 840

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 365 are 5 x 73

Prime factors of 839 are 839

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 651, 365, 839, 840

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

Apply this formula for all numbers.

Step1:

LCM(651, 365) = 237615

GCD(651, 365) = ( 651 x 365 ) / 237615

= 651 / 365

= 651

Step2:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 651, 365, 839, 840 is 1
