GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 448) = 144704
GCD(646, 448) = ( 646 x 448 ) / 144704
= 646 / 448
= 646
Step2:
LCM(2, 666) = 666
GCD(2, 666) = ( 2 x 666 ) / 666
= 2 / 666
= 2
Step3:
LCM(2, 574) = 574
GCD(2, 574) = ( 2 x 574 ) / 574
= 2 / 574
= 2
So, Greatest Common Divisor of 646, 448, 666, 574 is 2
