Given numbers are 890, 155, 250, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 155) = 27590
GCD(890, 155) = ( 890 x 155 ) / 27590
= 890 / 155
= 890
Step2:
LCM(5, 250) = 250
GCD(5, 250) = ( 5 x 250 ) / 250
= 5 / 250
= 5
Step3:
LCM(5, 809) = 4045
GCD(5, 809) = ( 5 x 809 ) / 4045
= 5 / 809
= 5
So, Greatest Common Divisor of 890, 155, 250, 809 is 1
