Given numbers are 990, 650, 819, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 650) = 64350
GCD(990, 650) = ( 990 x 650 ) / 64350
= 990 / 650
= 990
Step2:
LCM(10, 819) = 8190
GCD(10, 819) = ( 10 x 819 ) / 8190
= 10 / 819
= 10
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 990, 650, 819, 687 is 1
