Steps to Calculate GCD of 505, 147, 707, 389 using LCM Formula
Given numbers are 505, 147, 707, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(505, 147) = 74235
GCD(505, 147) = ( 505 x 147 ) / 74235
= 505 / 147
= 505
Step2:
LCM(1, 707) = 707
GCD(1, 707) = ( 1 x 707 ) / 707
= 1 / 707
= 1
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 505, 147, 707, 389 is 1
