Steps to Calculate GCD of 142, 507, 398, 449 using LCM Formula
Given numbers are 142, 507, 398, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 507) = 71994
GCD(142, 507) = ( 142 x 507 ) / 71994
= 142 / 507
= 142
Step2:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 142, 507, 398, 449 is 1
