Given numbers are 434, 642, 365, 147

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 642 are 2 x 3 x 107

Prime factors of 365 are 5 x 73

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 434, 642, 365, 147

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

Apply this formula for all numbers.

Step1:

LCM(434, 642) = 139314

GCD(434, 642) = ( 434 x 642 ) / 139314

= 434 / 642

= 434

Step2:

LCM(2, 365) = 730

GCD(2, 365) = ( 2 x 365 ) / 730

= 2 / 365

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 434, 642, 365, 147 is 1
