GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 837) = 232686
GCD(278, 837) = ( 278 x 837 ) / 232686
= 278 / 837
= 278
Step2:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 278, 837, 477, 247 is 1
