Given numbers are 654, 721, 462, 784

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 721 are 7 x 103

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 654, 721, 462, 784

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

Apply this formula for all numbers.

Step1:

LCM(654, 721) = 471534

GCD(654, 721) = ( 654 x 721 ) / 471534

= 654 / 721

= 654

Step2:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 654, 721, 462, 784 is 1
