Given numbers are 266, 720, 387, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(266, 720) = 95760
GCD(266, 720) = ( 266 x 720 ) / 95760
= 266 / 720
= 266
Step2:
LCM(2, 387) = 774
GCD(2, 387) = ( 2 x 387 ) / 774
= 2 / 387
= 2
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 266, 720, 387, 890 is 1
