Steps to Calculate GCD of 155, 530, 423, 766 using LCM Formula
Given numbers are 155, 530, 423, 766
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 530) = 16430
GCD(155, 530) = ( 155 x 530 ) / 16430
= 155 / 530
= 155
Step2:
LCM(5, 423) = 2115
GCD(5, 423) = ( 5 x 423 ) / 2115
= 5 / 423
= 5
Step3:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
So, Greatest Common Divisor of 155, 530, 423, 766 is 1
