Given numbers are 126, 870, 990, 208
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 870) = 18270
GCD(126, 870) = ( 126 x 870 ) / 18270
= 126 / 870
= 126
Step2:
LCM(6, 990) = 990
GCD(6, 990) = ( 6 x 990 ) / 990
= 6 / 990
= 6
Step3:
LCM(6, 208) = 624
GCD(6, 208) = ( 6 x 208 ) / 624
= 6 / 208
= 6
So, Greatest Common Divisor of 126, 870, 990, 208 is 2
