Given numbers are 728, 407, 398, 841
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 407) = 296296
GCD(728, 407) = ( 728 x 407 ) / 296296
= 728 / 407
= 728
Step2:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
Step3:
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
= 1 / 841
= 1
So, Greatest Common Divisor of 728, 407, 398, 841 is 1
