Given numbers are 219, 455, 557, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(219, 455) = 99645
GCD(219, 455) = ( 219 x 455 ) / 99645
= 219 / 455
= 219
Step2:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 219, 455, 557, 405 is 1
