Given numbers are 643,524,655,603

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

The LCM of 643,524,655,603 is 1015849980.

Find LCM of 643,524,655,603 with Prime Factorization

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

131 x 643 x 4 x 5 x 603 = 1015849980

Therefore, the lowest common multiple of 643,524,655,603 is 1015849980.

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.

643 x 524 x 655 x 603 = 133076347380

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.

643 : 1, 643

524 : 1, 2, 4, 131, 262, 524

655 : 1, 5, 131, 655

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,524,655,603, is 1.

Now, the common factors can be found like this.

643:643

524:2x 2x 131

655:5x 131

603:3x 3x 67

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

131 = 131

Therefore, the value for common factors is 131.

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 = 133076347380/(1x131)

LCM = 133076347380/131

LCM = 1015849980

Thus, we can understand that the LCM of 643,524,655,603 is 1015849980.
