GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 621) = 92529
GCD(447, 621) = ( 447 x 621 ) / 92529
= 447 / 621
= 447
Step2:
LCM(3, 570) = 570
GCD(3, 570) = ( 3 x 570 ) / 570
= 3 / 570
= 3
Step3:
LCM(3, 657) = 657
GCD(3, 657) = ( 3 x 657 ) / 657
= 3 / 657
= 3
So, Greatest Common Divisor of 447, 621, 570, 657 is 3
