Given numbers are 402,274,221,778

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

The LCM of 402,274,221,778 is 4734656706.

Find LCM of 402,274,221,778 with Prime Factorization

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

2 x 201 x 137 x 221 x 389 = 4734656706

Therefore, the lowest common multiple of 402,274,221,778 is 4734656706.

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.

402 x 274 x 221 x 778 = 18938626824

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

274 : 1, 2, 137, 274

221 : 1, 13, 17, 221

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,274,221,778, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

274:2x 137

221:13x 17

778:2x 389

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 18938626824/(1x4)

LCM = 18938626824/4

LCM = 4734656706

Thus, we can understand that the LCM of 402,274,221,778 is 4734656706.
