GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(284, 878) = 124676
GCD(284, 878) = ( 284 x 878 ) / 124676
= 284 / 878
= 284
Step2:
LCM(2, 187) = 374
GCD(2, 187) = ( 2 x 187 ) / 374
= 2 / 187
= 2
Step3:
LCM(1, 400) = 400
GCD(1, 400) = ( 1 x 400 ) / 400
= 1 / 400
= 1
So, Greatest Common Divisor of 284, 878, 187, 400 is 1
