Steps to Calculate GCD of 623, 197, 71, 770 using LCM Formula
Given numbers are 623, 197, 71, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 197) = 122731
GCD(623, 197) = ( 623 x 197 ) / 122731
= 623 / 197
= 623
Step2:
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
= 1 / 71
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 623, 197, 71, 770 is 1
