Given numbers are 278, 119, 780, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 119) = 33082
GCD(278, 119) = ( 278 x 119 ) / 33082
= 278 / 119
= 278
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 278, 119, 780, 401 is 1
