Steps to Calculate GCD of 154, 343, 70, 787 using LCM Formula
Given numbers are 154, 343, 70, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 343) = 7546
GCD(154, 343) = ( 154 x 343 ) / 7546
= 154 / 343
= 154
Step2:
LCM(7, 70) = 70
GCD(7, 70) = ( 7 x 70 ) / 70
= 7 / 70
= 7
Step3:
LCM(7, 787) = 5509
GCD(7, 787) = ( 7 x 787 ) / 5509
= 7 / 787
= 7
So, Greatest Common Divisor of 154, 343, 70, 787 is 1
