Given numbers are 345, 963, 561, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 963) = 110745
GCD(345, 963) = ( 345 x 963 ) / 110745
= 345 / 963
= 345
Step2:
LCM(3, 561) = 561
GCD(3, 561) = ( 3 x 561 ) / 561
= 3 / 561
= 3
Step3:
LCM(3, 158) = 474
GCD(3, 158) = ( 3 x 158 ) / 474
= 3 / 158
= 3
So, Greatest Common Divisor of 345, 963, 561, 158 is 1
