Given numbers are 561, 114, 171, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 114) = 21318
GCD(561, 114) = ( 561 x 114 ) / 21318
= 561 / 114
= 561
Step2:
LCM(3, 171) = 171
GCD(3, 171) = ( 3 x 171 ) / 171
= 3 / 171
= 3
Step3:
LCM(3, 445) = 1335
GCD(3, 445) = ( 3 x 445 ) / 1335
= 3 / 445
= 3
So, Greatest Common Divisor of 561, 114, 171, 445 is 1
