Given numbers are 347, 770, 865, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(347, 770) = 267190
GCD(347, 770) = ( 347 x 770 ) / 267190
= 347 / 770
= 347
Step2:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 347, 770, 865, 561 is 1
