Given numbers are 405, 174, 557, 864
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 174) = 23490
GCD(405, 174) = ( 405 x 174 ) / 23490
= 405 / 174
= 405
Step2:
LCM(3, 557) = 1671
GCD(3, 557) = ( 3 x 557 ) / 1671
= 3 / 557
= 3
Step3:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
So, Greatest Common Divisor of 405, 174, 557, 864 is 1
