Given numbers are 447, 369, 265, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 369) = 54981
GCD(447, 369) = ( 447 x 369 ) / 54981
= 447 / 369
= 447
Step2:
LCM(3, 265) = 795
GCD(3, 265) = ( 3 x 265 ) / 795
= 3 / 265
= 3
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 447, 369, 265, 621 is 1
