GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 650) = 216450
GCD(666, 650) = ( 666 x 650 ) / 216450
= 666 / 650
= 666
Step2:
LCM(2, 258) = 258
GCD(2, 258) = ( 2 x 258 ) / 258
= 2 / 258
= 2
Step3:
LCM(2, 838) = 838
GCD(2, 838) = ( 2 x 838 ) / 838
= 2 / 838
= 2
So, Greatest Common Divisor of 666, 650, 258, 838 is 2
