Given numbers are 690, 908, 859, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 908) = 313260
GCD(690, 908) = ( 690 x 908 ) / 313260
= 690 / 908
= 690
Step2:
LCM(2, 859) = 1718
GCD(2, 859) = ( 2 x 859 ) / 1718
= 2 / 859
= 2
Step3:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
So, Greatest Common Divisor of 690, 908, 859, 165 is 1
