Steps to Calculate GCD of 791, 815, 247, 423 using LCM Formula
Given numbers are 791, 815, 247, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 815) = 644665
GCD(791, 815) = ( 791 x 815 ) / 644665
= 791 / 815
= 791
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 791, 815, 247, 423 is 1
