GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 414) = 184230
GCD(890, 414) = ( 890 x 414 ) / 184230
= 890 / 414
= 890
Step2:
LCM(2, 819) = 1638
GCD(2, 819) = ( 2 x 819 ) / 1638
= 2 / 819
= 2
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 890, 414, 819, 728 is 1
