GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 156) = 65676
GCD(842, 156) = ( 842 x 156 ) / 65676
= 842 / 156
= 842
Step2:
LCM(2, 846) = 846
GCD(2, 846) = ( 2 x 846 ) / 846
= 2 / 846
= 2
Step3:
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
= 2 / 278
= 2
So, Greatest Common Divisor of 842, 156, 846, 278 is 2
