Steps to Calculate GCD of 248, 666, 81, 245 using LCM Formula
Given numbers are 248, 666, 81, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(248, 666) = 82584
GCD(248, 666) = ( 248 x 666 ) / 82584
= 248 / 666
= 248
Step2:
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
= 2 / 81
= 2
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 248, 666, 81, 245 is 1
