Given numbers are 630, 535, 406, 781

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 535 are 5 x 107

Prime factors of 406 are 2 x 7 x 29

Prime factors of 781 are 11 x 71

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

Given numbers are 630, 535, 406, 781

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

Apply this formula for all numbers.

Step1:

LCM(630, 535) = 67410

GCD(630, 535) = ( 630 x 535 ) / 67410

= 630 / 535

= 630

Step2:

LCM(5, 406) = 2030

GCD(5, 406) = ( 5 x 406 ) / 2030

= 5 / 406

= 5

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 630, 535, 406, 781 is 1
