Given numbers are 217,155,862,557

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

The LCM of 217,155,862,557 is 520945390.

Find LCM of 217,155,862,557 with Prime Factorization

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

31 x 7 x 5 x 862 x 557 = 520945390

Therefore, the lowest common multiple of 217,155,862,557 is 520945390.

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.

217 x 155 x 862 x 557 = 16149307090

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.

217 : 1, 7, 31, 217

155 : 1, 5, 31, 155

862 : 1, 2, 431, 862

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,155,862,557, is 1.

Now, the common factors can be found like this.

217:7x 31

155:5x 31

862:2x 431

557:557

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 = 16149307090/(1x31)

LCM = 16149307090/31

LCM = 520945390

Thus, we can understand that the LCM of 217,155,862,557 is 520945390.
