Given numbers are 890, 650, 430, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 650) = 57850
GCD(890, 650) = ( 890 x 650 ) / 57850
= 890 / 650
= 890
Step2:
LCM(10, 430) = 430
GCD(10, 430) = ( 10 x 430 ) / 430
= 10 / 430
= 10
Step3:
LCM(10, 280) = 280
GCD(10, 280) = ( 10 x 280 ) / 280
= 10 / 280
= 10
So, Greatest Common Divisor of 890, 650, 430, 280 is 10
