Given numbers are 706,118,221,643

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

The LCM of 706,118,221,643 is 5919158362.

Find LCM of 706,118,221,643 with Prime Factorization

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

2 x 353 x 59 x 221 x 643 = 5919158362

Therefore, the lowest common multiple of 706,118,221,643 is 5919158362.

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.

706 x 118 x 221 x 643 = 11838316724

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.

706 : 1, 2, 353, 706

118 : 1, 2, 59, 118

221 : 1, 13, 17, 221

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,118,221,643, is 1.

Now, the common factors can be found like this.

706:2x 353

118:2x 59

221:13x 17

643:643

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 = 11838316724/(1x2)

LCM = 11838316724/2

LCM = 5919158362

Thus, we can understand that the LCM of 706,118,221,643 is 5919158362.
