GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 641) = 178198
GCD(278, 641) = ( 278 x 641 ) / 178198
= 278 / 641
= 278
Step2:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
Step3:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
So, Greatest Common Divisor of 278, 641, 419, 828 is 1
