Given numbers are 261, 155, 347, 270
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 155) = 40455
GCD(261, 155) = ( 261 x 155 ) / 40455
= 261 / 155
= 261
Step2:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
Step3:
LCM(1, 270) = 270
GCD(1, 270) = ( 1 x 270 ) / 270
= 1 / 270
= 1
So, Greatest Common Divisor of 261, 155, 347, 270 is 1
