Steps to Calculate GCD of 391, 530, 25, 783 using LCM Formula
Given numbers are 391, 530, 25, 783
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 530) = 207230
GCD(391, 530) = ( 391 x 530 ) / 207230
= 391 / 530
= 391
Step2:
LCM(1, 25) = 25
GCD(1, 25) = ( 1 x 25 ) / 25
= 1 / 25
= 1
Step3:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
So, Greatest Common Divisor of 391, 530, 25, 783 is 1
