GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(849, 216) = 61128
GCD(849, 216) = ( 849 x 216 ) / 61128
= 849 / 216
= 849
Step2:
LCM(3, 156) = 156
GCD(3, 156) = ( 3 x 156 ) / 156
= 3 / 156
= 3
Step3:
LCM(3, 870) = 870
GCD(3, 870) = ( 3 x 870 ) / 870
= 3 / 870
= 3
So, Greatest Common Divisor of 849, 216, 156, 870 is 3
