Steps to Calculate GCD of 155, 207, 573, 991 using LCM Formula
Given numbers are 155, 207, 573, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 207) = 32085
GCD(155, 207) = ( 155 x 207 ) / 32085
= 155 / 207
= 155
Step2:
LCM(1, 573) = 573
GCD(1, 573) = ( 1 x 573 ) / 573
= 1 / 573
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 155, 207, 573, 991 is 1
