Given numbers are 691,386,603,965

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

The LCM of 691,386,603,965 is 804178890.

Find LCM of 691,386,603,965 with Prime Factorization

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

193 x 691 x 2 x 603 x 5 = 804178890

Therefore, the lowest common multiple of 691,386,603,965 is 804178890.

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.

691 x 386 x 603 x 965 = 155206525770

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.

691 : 1, 691

386 : 1, 2, 193, 386

603 : 1, 3, 9, 67, 201, 603

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,386,603,965, is 1.

Now, the common factors can be found like this.

691:691

386:2x 193

603:3x 3x 67

965:5x 193

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

193 = 193

Therefore, the value for common factors is 193.

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 = 155206525770/(1x193)

LCM = 155206525770/193

LCM = 804178890

Thus, we can understand that the LCM of 691,386,603,965 is 804178890.
