Given numbers are 898, 648, 381, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(898, 648) = 290952
GCD(898, 648) = ( 898 x 648 ) / 290952
= 898 / 648
= 898
Step2:
LCM(2, 381) = 762
GCD(2, 381) = ( 2 x 381 ) / 762
= 2 / 381
= 2
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 898, 648, 381, 789 is 1
