Steps to Calculate GCD of 643, 247, 33, 101 using LCM Formula
Given numbers are 643, 247, 33, 101
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 247) = 158821
GCD(643, 247) = ( 643 x 247 ) / 158821
= 643 / 247
= 643
Step2:
LCM(1, 33) = 33
GCD(1, 33) = ( 1 x 33 ) / 33
= 1 / 33
= 1
Step3:
LCM(1, 101) = 101
GCD(1, 101) = ( 1 x 101 ) / 101
= 1 / 101
= 1
So, Greatest Common Divisor of 643, 247, 33, 101 is 1
