Prime factors of 286 are 2 x 11 x 13
Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 115, 400, 286, 480
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 400) = 9200
GCD(115, 400) = ( 115 x 400 ) / 9200
= 115 / 400
= 115
Step2:
LCM(5, 286) = 1430
GCD(5, 286) = ( 5 x 286 ) / 1430
= 5 / 286
= 5
Step3:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
So, Greatest Common Divisor of 115, 400, 286, 480 is 1
