The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 956 are 2 x 2 x 239
Prime factors of 403 are 13 x 31
Prime factors of 478 are 2 x 239
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 956, 403, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 956) = 200760
GCD(840, 956) = ( 840 x 956 ) / 200760
= 840 / 956
= 840
Step2:
LCM(4, 403) = 1612
GCD(4, 403) = ( 4 x 403 ) / 1612
= 4 / 403
= 4
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 840, 956, 403, 478 is 1
