Given numbers are 645, 963, 540, 436

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 963 are 3 x 3 x 107

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 436 are 2 x 2 x 109

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

Given numbers are 645, 963, 540, 436

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

Apply this formula for all numbers.

Step1:

LCM(645, 963) = 207045

GCD(645, 963) = ( 645 x 963 ) / 207045

= 645 / 963

= 645

Step2:

LCM(3, 540) = 540

GCD(3, 540) = ( 3 x 540 ) / 540

= 3 / 540

= 3

Step3:

LCM(3, 436) = 1308

GCD(3, 436) = ( 3 x 436 ) / 1308

= 3 / 436

= 3

So, Greatest Common Divisor of 645, 963, 540, 436 is 1
