Given numbers are 515, 216, 869, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 216) = 111240
GCD(515, 216) = ( 515 x 216 ) / 111240
= 515 / 216
= 515
Step2:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 515, 216, 869, 280 is 1
