Given numbers are 280, 555, 574, 749
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 555) = 31080
GCD(280, 555) = ( 280 x 555 ) / 31080
= 280 / 555
= 280
Step2:
LCM(5, 574) = 2870
GCD(5, 574) = ( 5 x 574 ) / 2870
= 5 / 574
= 5
Step3:
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
= 1 / 749
= 1
So, Greatest Common Divisor of 280, 555, 574, 749 is 1
