GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(368, 668) = 61456
GCD(368, 668) = ( 368 x 668 ) / 61456
= 368 / 668
= 368
Step2:
LCM(4, 686) = 1372
GCD(4, 686) = ( 4 x 686 ) / 1372
= 4 / 686
= 4
Step3:
LCM(2, 432) = 432
GCD(2, 432) = ( 2 x 432 ) / 432
= 2 / 432
= 2
So, Greatest Common Divisor of 368, 668, 686, 432 is 2
