Given numbers are 617,628,126,787

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

The LCM of 617,628,126,787 is 19211447556.

Find LCM of 617,628,126,787 with Prime Factorization

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

2 x 617 x 314 x 63 x 787 = 19211447556

Therefore, the lowest common multiple of 617,628,126,787 is 19211447556.

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.

617 x 628 x 126 x 787 = 38422895112

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.

617 : 1, 617

628 : 1, 2, 4, 157, 314, 628

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,628,126,787, is 1.

Now, the common factors can be found like this.

617:617

628:2x 2x 157

126:2x 3x 3x 7

787:787

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

2 = 2

Therefore, the value for common factors is 2.

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 = 38422895112/(1x2)

LCM = 38422895112/2

LCM = 19211447556

Thus, we can understand that the LCM of 617,628,126,787 is 19211447556.
