Steps to Calculate GCD of 831, 787, 751, 142 using LCM Formula
Given numbers are 831, 787, 751, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 787) = 653997
GCD(831, 787) = ( 831 x 787 ) / 653997
= 831 / 787
= 831
Step2:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 831, 787, 751, 142 is 1
