Steps to Calculate GCD of 63, 81, 82, 72 using LCM Formula

Given numbers are 63, 81, 82, 72

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

Apply this formula for all numbers.

Step1:

LCM(63, 81) = 567

GCD(63, 81) = ( 63 x 81 ) / 567

= 63 / 81

= 63


Step2:

LCM(9, 82) = 738

GCD(9, 82) = ( 9 x 82 ) / 738

= 9 / 82

= 9


Step3:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1


So, Greatest Common Divisor of 63, 81, 82, 72 is 1
