GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 878) = 275692
GCD(628, 878) = ( 628 x 878 ) / 275692
= 628 / 878
= 628
Step2:
LCM(2, 896) = 896
GCD(2, 896) = ( 2 x 896 ) / 896
= 2 / 896
= 2
Step3:
LCM(2, 669) = 1338
GCD(2, 669) = ( 2 x 669 ) / 1338
= 2 / 669
= 2
So, Greatest Common Divisor of 628, 878, 896, 669 is 1
