Given numbers are 680,691,248,219

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

The LCM of 680,691,248,219 is 3190015320.

Find LCM of 680,691,248,219 with Prime Factorization

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

2 x 2 x 2 x 85 x 691 x 31 x 219 = 3190015320

Therefore, the lowest common multiple of 680,691,248,219 is 3190015320.

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.

680 x 691 x 248 x 219 = 25520122560

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

691 : 1, 691

248 : 1, 2, 4, 8, 31, 62, 124, 248

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,691,248,219, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

691:691

248:2x 2x 2x 31

219:3x 73

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 25520122560/(1x8)

LCM = 25520122560/8

LCM = 3190015320

Thus, we can understand that the LCM of 680,691,248,219 is 3190015320.
