Steps to Calculate GCD of 838, 798, 139, 247 using LCM Formula
Given numbers are 838, 798, 139, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 798) = 334362
GCD(838, 798) = ( 838 x 798 ) / 334362
= 838 / 798
= 838
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 838, 798, 139, 247 is 1
