Given numbers are 302, 221, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(302, 221) = 66742
GCD(302, 221) = ( 302 x 221 ) / 66742
= 302 / 221
= 302
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 302, 221, 840 is 1
