Given numbers are 321, 102, 165, 653
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 102) = 10914
GCD(321, 102) = ( 321 x 102 ) / 10914
= 321 / 102
= 321
Step2:
LCM(3, 165) = 165
GCD(3, 165) = ( 3 x 165 ) / 165
= 3 / 165
= 3
Step3:
LCM(3, 653) = 1959
GCD(3, 653) = ( 3 x 653 ) / 1959
= 3 / 653
= 3
So, Greatest Common Divisor of 321, 102, 165, 653 is 1
