Given numbers are 728, 910, 485, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 910) = 3640
GCD(728, 910) = ( 728 x 910 ) / 3640
= 728 / 910
= 728
Step2:
LCM(182, 485) = 88270
GCD(182, 485) = ( 182 x 485 ) / 88270
= 182 / 485
= 182
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 728, 910, 485, 643 is 1
