Steps to Calculate GCD of 215, 395, 142, 787 using LCM Formula
Given numbers are 215, 395, 142, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 395) = 16985
GCD(215, 395) = ( 215 x 395 ) / 16985
= 215 / 395
= 215
Step2:
LCM(5, 142) = 710
GCD(5, 142) = ( 5 x 142 ) / 710
= 5 / 142
= 5
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 215, 395, 142, 787 is 1
