GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 666) = 23310
GCD(630, 666) = ( 630 x 666 ) / 23310
= 630 / 666
= 630
Step2:
LCM(18, 620) = 5580
GCD(18, 620) = ( 18 x 620 ) / 5580
= 18 / 620
= 18
Step3:
LCM(2, 958) = 958
GCD(2, 958) = ( 2 x 958 ) / 958
= 2 / 958
= 2
So, Greatest Common Divisor of 630, 666, 620, 958 is 2
