Given numbers are 549, 135, 345, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 135) = 8235
GCD(549, 135) = ( 549 x 135 ) / 8235
= 549 / 135
= 549
Step2:
LCM(9, 345) = 1035
GCD(9, 345) = ( 9 x 345 ) / 1035
= 9 / 345
= 9
Step3:
LCM(3, 419) = 1257
GCD(3, 419) = ( 3 x 419 ) / 1257
= 3 / 419
= 3
So, Greatest Common Divisor of 549, 135, 345, 419 is 1
