Given numbers are 851,851,987,661

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

The LCM of 851,851,987,661 is 555198357.

Find LCM of 851,851,987,661 with Prime Factorization

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

23 x 37 x 1 x 1 x 987 x 661 = 555198357

Therefore, the lowest common multiple of 851,851,987,661 is 555198357.

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.

851 x 851 x 987 x 661 = 472473801807

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.

851 : 1, 23, 37, 851

851 : 1, 23, 37, 851

987 : 1, 3, 7, 21, 47, 141, 329, 987

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,851,987,661, is 1.

Now, the common factors can be found like this.

851:23x 37

851:23x 37

987:3x 7x 47

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.

23x 37 = 851

Therefore, the value for common factors is 851.

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 = 472473801807/(1x851)

LCM = 472473801807/851

LCM = 555198357

Thus, we can understand that the LCM of 851,851,987,661 is 555198357.
