GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 555) = 12765
GCD(345, 555) = ( 345 x 555 ) / 12765
= 345 / 555
= 345
Step2:
LCM(15, 981) = 4905
GCD(15, 981) = ( 15 x 981 ) / 4905
= 15 / 981
= 15
Step3:
LCM(3, 462) = 462
GCD(3, 462) = ( 3 x 462 ) / 462
= 3 / 462
= 3
So, Greatest Common Divisor of 345, 555, 981, 462 is 3
