Given numbers are 406, 708, 965, 490

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 708 are 2 x 2 x 3 x 59

Prime factors of 965 are 5 x 193

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 406, 708, 965, 490

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

Apply this formula for all numbers.

Step1:

LCM(406, 708) = 143724

GCD(406, 708) = ( 406 x 708 ) / 143724

= 406 / 708

= 406

Step2:

LCM(2, 965) = 1930

GCD(2, 965) = ( 2 x 965 ) / 1930

= 2 / 965

= 2

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 406, 708, 965, 490 is 1
