Given numbers are 280, 918, 312, 871
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 918) = 128520
GCD(280, 918) = ( 280 x 918 ) / 128520
= 280 / 918
= 280
Step2:
LCM(2, 312) = 312
GCD(2, 312) = ( 2 x 312 ) / 312
= 2 / 312
= 2
Step3:
LCM(2, 871) = 1742
GCD(2, 871) = ( 2 x 871 ) / 1742
= 2 / 871
= 2
So, Greatest Common Divisor of 280, 918, 312, 871 is 1
