Steps to Calculate GCD of 145, 355, 634, 663 using LCM Formula
Given numbers are 145, 355, 634, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 355) = 10295
GCD(145, 355) = ( 145 x 355 ) / 10295
= 145 / 355
= 145
Step2:
LCM(5, 634) = 3170
GCD(5, 634) = ( 5 x 634 ) / 3170
= 5 / 634
= 5
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 145, 355, 634, 663 is 1
