Given numbers are 515, 270, 857, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 270) = 27810
GCD(515, 270) = ( 515 x 270 ) / 27810
= 515 / 270
= 515
Step2:
LCM(5, 857) = 4285
GCD(5, 857) = ( 5 x 857 ) / 4285
= 5 / 857
= 5
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 515, 270, 857, 120 is 1
