The LCM of 3,5,7,13 is?

4 Answers

  • 3,5,7 and 13 in this group of numbers , each number is a prime number and none of them are divisible by any of the given numbers , so there is no common divisible number , and therfore we have to multiply all of them to get Prime Number , that is 3 x 5 x7 x 13 = 1365. To cross varify we can take each no by dividing prime number by given no, say , 1365/3= 455 , so it is divisible , similarly with no 7 , 1365 /7 = 195 , follwed by no , 13 , it is 1385/13 = 105 , so prime no 1365 is lcm for given numbers

  • 1365

    Because they are all co-primes (they have no common factor) then multiply all the numbers.

    3*5*7*13= 15*7*13= 15*91= 1365.

  • They are all prime so just multiply them together
