Given numbers are 407,402,973,556

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

The LCM of 407,402,973,556 is 318392844.

Find LCM of 407,402,973,556 with Prime Factorization

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

2 x 139 x 407 x 201 x 7 x 2 = 318392844

Therefore, the lowest common multiple of 407,402,973,556 is 318392844.

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.

407 x 402 x 973 x 556 = 88513210632

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.

407 : 1, 11, 37, 407

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

973 : 1, 7, 139, 973

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,402,973,556, is 1.

Now, the common factors can be found like this.

407:11x 37

402:2x 3x 67

973:7x 139

556:2x 2x 139

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

2x 139 = 278

Therefore, the value for common factors is 278.

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 = 88513210632/(1x278)

LCM = 88513210632/278

LCM = 318392844

Thus, we can understand that the LCM of 407,402,973,556 is 318392844.
