Given numbers are 117,248,217,661

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

The LCM of 117,248,217,661 is 134257032.

Find LCM of 117,248,217,661 with Prime Factorization

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

31 x 117 x 8 x 7 x 661 = 134257032

Therefore, the lowest common multiple of 117,248,217,661 is 134257032.

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.

117 x 248 x 217 x 661 = 4161967992

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.

117 : 1, 3, 9, 13, 39, 117

248 : 1, 2, 4, 8, 31, 62, 124, 248

217 : 1, 7, 31, 217

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,248,217,661, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

248:2x 2x 2x 31

217:7x 31

661:661

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 = 4161967992/(1x31)

LCM = 4161967992/31

LCM = 134257032

Thus, we can understand that the LCM of 117,248,217,661 is 134257032.
