GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 870) = 280140
GCD(644, 870) = ( 644 x 870 ) / 280140
= 644 / 870
= 644
Step2:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
Step3:
LCM(2, 232) = 232
GCD(2, 232) = ( 2 x 232 ) / 232
= 2 / 232
= 2
So, Greatest Common Divisor of 644, 870, 406, 232 is 2
