Given numbers are 851,185,921,821

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

The LCM of 851,185,921,821 is 3217379955.

Find LCM of 851,185,921,821 with Prime Factorization

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

37 x 23 x 5 x 921 x 821 = 3217379955

Therefore, the lowest common multiple of 851,185,921,821 is 3217379955.

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 185 x 921 x 821 = 119043058335

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

185 : 1, 5, 37, 185

921 : 1, 3, 307, 921

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,185,921,821, is 1.

Now, the common factors can be found like this.

851:23x 37

185:5x 37

921:3x 307

821:821

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

37 = 37

Therefore, the value for common factors is 37.

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 = 119043058335/(1x37)

LCM = 119043058335/37

LCM = 3217379955

Thus, we can understand that the LCM of 851,185,921,821 is 3217379955.
