Given numbers are 909, 690, 887, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 690) = 209070
GCD(909, 690) = ( 909 x 690 ) / 209070
= 909 / 690
= 909
Step2:
LCM(3, 887) = 2661
GCD(3, 887) = ( 3 x 887 ) / 2661
= 3 / 887
= 3
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 909, 690, 887, 806 is 1
