GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(158, 286) = 22594
GCD(158, 286) = ( 158 x 286 ) / 22594
= 158 / 286
= 158
Step2:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
Step3:
LCM(2, 855) = 1710
GCD(2, 855) = ( 2 x 855 ) / 1710
= 2 / 855
= 2
So, Greatest Common Divisor of 158, 286, 942, 855 is 1
