Given numbers are 417, 405, 860, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 405) = 56295
GCD(417, 405) = ( 417 x 405 ) / 56295
= 417 / 405
= 417
Step2:
LCM(3, 860) = 2580
GCD(3, 860) = ( 3 x 860 ) / 2580
= 3 / 860
= 3
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 417, 405, 860, 663 is 1
