Given numbers are 270, 105, 515, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 105) = 1890
GCD(270, 105) = ( 270 x 105 ) / 1890
= 270 / 105
= 270
Step2:
LCM(15, 515) = 1545
GCD(15, 515) = ( 15 x 515 ) / 1545
= 15 / 515
= 15
Step3:
LCM(5, 840) = 840
GCD(5, 840) = ( 5 x 840 ) / 840
= 5 / 840
= 5
So, Greatest Common Divisor of 270, 105, 515, 840 is 5
