Given numbers are 73, 63, 74, 21
The list of prime factors of all numbers are
Prime factors of 73 are 73
Prime factors of 63 are 3 x 3 x 7
Prime factors of 74 are 2 x 37
Prime factors of 21 are 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 73, 63, 74, 21 using LCM Formula
Given numbers are 73, 63, 74, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(73, 63) = 4599
GCD(73, 63) = ( 73 x 63 ) / 4599
= 73 / 63
= 73
Step2:
LCM(1, 74) = 74
GCD(1, 74) = ( 1 x 74 ) / 74
= 1 / 74
= 1
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 73, 63, 74, 21 is 1
