GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 834) = 834
GCD(278, 834) = ( 278 x 834 ) / 834
= 278 / 834
= 278
Step2:
LCM(278, 911) = 253258
GCD(278, 911) = ( 278 x 911 ) / 253258
= 278 / 911
= 278
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 278, 834, 911, 561 is 1
