Given numbers are 430, 416, 313, 278
The list of prime factors of all numbers are
Prime factors of 430 are 2 x 5 x 43
Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13
Prime factors of 313 are 313
Prime factors of 278 are 2 x 139
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 430, 416, 313, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 416) = 89440
GCD(430, 416) = ( 430 x 416 ) / 89440
= 430 / 416
= 430
Step2:
LCM(2, 313) = 626
GCD(2, 313) = ( 2 x 313 ) / 626
= 2 / 313
= 2
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 430, 416, 313, 278 is 1
