Given numbers are 756, 654, 870, 445

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 654 are 2 x 3 x 109

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 445 are 5 x 89

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

Given numbers are 756, 654, 870, 445

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

Apply this formula for all numbers.

Step1:

LCM(756, 654) = 82404

GCD(756, 654) = ( 756 x 654 ) / 82404

= 756 / 654

= 756

Step2:

LCM(6, 870) = 870

GCD(6, 870) = ( 6 x 870 ) / 870

= 6 / 870

= 6

Step3:

LCM(6, 445) = 2670

GCD(6, 445) = ( 6 x 445 ) / 2670

= 6 / 445

= 6

So, Greatest Common Divisor of 756, 654, 870, 445 is 1
