The list of prime factors of all numbers are
Prime factors of 381 are 3 x 127
Prime factors of 278 are 2 x 139
Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5
Prime factors of 286 are 2 x 11 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 381, 278, 480, 286
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 278) = 105918
GCD(381, 278) = ( 381 x 278 ) / 105918
= 381 / 278
= 381
Step2:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
Step3:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
So, Greatest Common Divisor of 381, 278, 480, 286 is 1
