GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 374) = 7106
GCD(646, 374) = ( 646 x 374 ) / 7106
= 646 / 374
= 646
Step2:
LCM(34, 216) = 3672
GCD(34, 216) = ( 34 x 216 ) / 3672
= 34 / 216
= 34
Step3:
LCM(2, 910) = 910
GCD(2, 910) = ( 2 x 910 ) / 910
= 2 / 910
= 2
So, Greatest Common Divisor of 646, 374, 216, 910 is 2
