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 868 are 2 x 2 x 7 x 31
Prime factors of 247 are 13 x 19
Prime factors of 913 are 11 x 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 868, 247, 913
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 868) = 86800
GCD(400, 868) = ( 400 x 868 ) / 86800
= 400 / 868
= 400
Step2:
LCM(4, 247) = 988
GCD(4, 247) = ( 4 x 247 ) / 988
= 4 / 247
= 4
Step3:
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
= 1 / 913
= 1
So, Greatest Common Divisor of 400, 868, 247, 913 is 1
