Steps to Calculate GCD of 245, 847, 143, 254 using LCM Formula
Given numbers are 245, 847, 143, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 847) = 29645
GCD(245, 847) = ( 245 x 847 ) / 29645
= 245 / 847
= 245
Step2:
LCM(7, 143) = 1001
GCD(7, 143) = ( 7 x 143 ) / 1001
= 7 / 143
= 7
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 245, 847, 143, 254 is 1
