Steps to Calculate GCD of 163, 997, 158, 181 using LCM Formula

Given numbers are 163, 997, 158, 181

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(163, 997) = 162511

GCD(163, 997) = ( 163 x 997 ) / 162511

= 163 / 997

= 163


Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1


Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1


So, Greatest Common Divisor of 163, 997, 158, 181 is 1
