Given numbers are 613, 653, 840, 436

The list of prime factors of all numbers are

Prime factors of 613 are 613

Prime factors of 653 are 653

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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 613, 653, 840, 436

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

Apply this formula for all numbers.

Step1:

LCM(613, 653) = 400289

GCD(613, 653) = ( 613 x 653 ) / 400289

= 613 / 653

= 613

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 613, 653, 840, 436 is 1
