Given numbers are 961,155,821,986

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

The LCM of 961,155,821,986 is 3889676330.

Find LCM of 961,155,821,986 with Prime Factorization

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

31 x 31 x 5 x 821 x 986 = 3889676330

Therefore, the lowest common multiple of 961,155,821,986 is 3889676330.

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.

961 x 155 x 821 x 986 = 120579966230

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.

961 : 1, 31, 961

155 : 1, 5, 31, 155

821 : 1, 821

986 : 1, 2, 17, 29, 34, 58, 493, 986

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,155,821,986, is 1.

Now, the common factors can be found like this.

961:31x 31

155:5x 31

821:821

986:2x 17x 29

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

31 = 31

Therefore, the value for common factors is 31.

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 = 120579966230/(1x31)

LCM = 120579966230/31

LCM = 3889676330

Thus, we can understand that the LCM of 961,155,821,986 is 3889676330.
