Given numbers are 721,365,817,219

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 721,365,817,219 is 645017415.

Find LCM of 721,365,817,219 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

73 x 721 x 5 x 817 x 3 = 645017415

Therefore, the lowest common multiple of 721,365,817,219 is 645017415.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

721 x 365 x 817 x 219 = 47086271295

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

721 : 1, 7, 103, 721

365 : 1, 5, 73, 365

817 : 1, 19, 43, 817

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,365,817,219, is 1.

Now, the common factors can be found like this.

721:7x 103

365:5x 73

817:19x 43

219:3x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

73 = 73

Therefore, the value for common factors is 73.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 47086271295/(1x73)

LCM = 47086271295/73

LCM = 645017415

Thus, we can understand that the LCM of 721,365,817,219 is 645017415.
