GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 861) = 43911
GCD(153, 861) = ( 153 x 861 ) / 43911
= 153 / 861
= 153
Step2:
LCM(3, 870) = 870
GCD(3, 870) = ( 3 x 870 ) / 870
= 3 / 870
= 3
Step3:
LCM(3, 968) = 2904
GCD(3, 968) = ( 3 x 968 ) / 2904
= 3 / 968
= 3
So, Greatest Common Divisor of 153, 861, 870, 968 is 1
