Given numbers are 286, 400, 980, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(286, 400) = 57200
GCD(286, 400) = ( 286 x 400 ) / 57200
= 286 / 400
= 286
Step2:
LCM(2, 980) = 980
GCD(2, 980) = ( 2 x 980 ) / 980
= 2 / 980
= 2
Step3:
LCM(2, 205) = 410
GCD(2, 205) = ( 2 x 205 ) / 410
= 2 / 205
= 2
So, Greatest Common Divisor of 286, 400, 980, 205 is 1
