Given numbers are 639,578,701,940,787

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

The LCM of 639,578,701,940,787 is 95767754578380.

Find LCM of 639,578,701,940,787 with Prime Factorization

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

2 x 639 x 289 x 701 x 470 x 787 = 95767754578380

Therefore, the lowest common multiple of 639,578,701,940,787 is 95767754578380.

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.

639 x 578 x 701 x 940 x 787 = 191535509156760

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.

639 : 1, 3, 9, 71, 213, 639

578 : 1, 2, 17, 34, 289, 578

701 : 1, 701

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,578,701,940,787, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

578:2x 17x 17

701:701

940:2x 2x 5x 47

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 = 191535509156760/(1x2)

LCM = 191535509156760/2

LCM = 95767754578380

Thus, we can understand that the LCM of 639,578,701,940,787 is 95767754578380.
