Given numbers are 461, 240, 247, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(461, 240) = 110640
GCD(461, 240) = ( 461 x 240 ) / 110640
= 461 / 240
= 461
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 461, 240, 247, 221 is 1
