Given numbers are 405, 655, 47, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 655) = 53055
GCD(405, 655) = ( 405 x 655 ) / 53055
= 405 / 655
= 405
Step2:
LCM(5, 47) = 235
GCD(5, 47) = ( 5 x 47 ) / 235
= 5 / 47
= 5
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 405, 655, 47, 542 is 1
