Steps to Calculate GCD of 620, 419, 987, 698 using LCM Formula
Given numbers are 620, 419, 987, 698
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 419) = 259780
GCD(620, 419) = ( 620 x 419 ) / 259780
= 620 / 419
= 620
Step2:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
Step3:
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
= 1 / 698
= 1
So, Greatest Common Divisor of 620, 419, 987, 698 is 1
