Given numbers are 412, 453, 421, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(412, 453) = 186636
GCD(412, 453) = ( 412 x 453 ) / 186636
= 412 / 453
= 412
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 412, 453, 421, 621 is 1
