Given numbers are 400, 538, 962, 455
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 538 are 2 x 269
Prime factors of 962 are 2 x 13 x 37
Prime factors of 455 are 5 x 7 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 538, 962, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 538) = 107600
GCD(400, 538) = ( 400 x 538 ) / 107600
= 400 / 538
= 400
Step2:
LCM(2, 962) = 962
GCD(2, 962) = ( 2 x 962 ) / 962
= 2 / 962
= 2
Step3:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
So, Greatest Common Divisor of 400, 538, 962, 455 is 1
