Steps to Calculate GCD of 371, 809, 642, 247 using LCM Formula
Given numbers are 371, 809, 642, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(371, 809) = 300139
GCD(371, 809) = ( 371 x 809 ) / 300139
= 371 / 809
= 371
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 371, 809, 642, 247 is 1
