Given numbers are 275, 280, 338, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(275, 280) = 15400
GCD(275, 280) = ( 275 x 280 ) / 15400
= 275 / 280
= 275
Step2:
LCM(5, 338) = 1690
GCD(5, 338) = ( 5 x 338 ) / 1690
= 5 / 338
= 5
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 275, 280, 338, 869 is 1
