Given numbers are 400, 811, 703, 630
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 811 are 811
Prime factors of 703 are 19 x 37
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 811, 703, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 811) = 324400
GCD(400, 811) = ( 400 x 811 ) / 324400
= 400 / 811
= 400
Step2:
LCM(1, 703) = 703
GCD(1, 703) = ( 1 x 703 ) / 703
= 1 / 703
= 1
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 400, 811, 703, 630 is 1
