Given numbers are 728, 262, 285, 418
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 262) = 95368
GCD(728, 262) = ( 728 x 262 ) / 95368
= 728 / 262
= 728
Step2:
LCM(2, 285) = 570
GCD(2, 285) = ( 2 x 285 ) / 570
= 2 / 285
= 2
Step3:
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
= 1 / 418
= 1
So, Greatest Common Divisor of 728, 262, 285, 418 is 1
