Given numbers are 730, 642, 267, 649

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 642 are 2 x 3 x 107

Prime factors of 267 are 3 x 89

Prime factors of 649 are 11 x 59

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

Given numbers are 730, 642, 267, 649

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

Apply this formula for all numbers.

Step1:

LCM(730, 642) = 234330

GCD(730, 642) = ( 730 x 642 ) / 234330

= 730 / 642

= 730

Step2:

LCM(2, 267) = 534

GCD(2, 267) = ( 2 x 267 ) / 534

= 2 / 267

= 2

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 730, 642, 267, 649 is 1
