Steps to Calculate GCD of 861, 833, 23, 247 using LCM Formula
Given numbers are 861, 833, 23, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 833) = 102459
GCD(861, 833) = ( 861 x 833 ) / 102459
= 861 / 833
= 861
Step2:
LCM(7, 23) = 161
GCD(7, 23) = ( 7 x 23 ) / 161
= 7 / 23
= 7
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 861, 833, 23, 247 is 1
