Given numbers are 961,614,247,155

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

The LCM of 961,614,247,155 is 728716690.

Find LCM of 961,614,247,155 with Prime Factorization

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

31 x 31 x 614 x 247 x 5 = 728716690

Therefore, the lowest common multiple of 961,614,247,155 is 728716690.

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 614 x 247 x 155 = 22590217390

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

614 : 1, 2, 307, 614

247 : 1, 13, 19, 247

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,614,247,155, is 1.

Now, the common factors can be found like this.

961:31x 31

614:2x 307

247:13x 19

155:5x 31

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 = 22590217390/(1x31)

LCM = 22590217390/31

LCM = 728716690

Thus, we can understand that the LCM of 961,614,247,155 is 728716690.
