Given numbers are 451, 720, 70, 678

The list of prime factors of all numbers are

Prime factors of 451 are 11 x 41

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 70 are 2 x 5 x 7

Prime factors of 678 are 2 x 3 x 113

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

Given numbers are 451, 720, 70, 678

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

Apply this formula for all numbers.

Step1:

LCM(451, 720) = 324720

GCD(451, 720) = ( 451 x 720 ) / 324720

= 451 / 720

= 451

Step2:

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

= 1 / 70

= 1

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 451, 720, 70, 678 is 1
