Given numbers are 685,146,290,254

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

The LCM of 685,146,290,254 is 368336830.

Find LCM of 685,146,290,254 with Prime Factorization

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

2 x 5 x 137 x 73 x 29 x 127 = 368336830

Therefore, the lowest common multiple of 685,146,290,254 is 368336830.

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.

685 x 146 x 290 x 254 = 7366736600

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.

685 : 1, 5, 137, 685

146 : 1, 2, 73, 146

290 : 1, 2, 5, 10, 29, 58, 145, 290

254 : 1, 2, 127, 254

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,146,290,254, is 1.

Now, the common factors can be found like this.

685:5x 137

146:2x 73

290:2x 5x 29

254:2x 127

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 5 = 20

Therefore, the value for common factors is 20.

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 = 7366736600/(1x20)

LCM = 7366736600/20

LCM = 368336830

Thus, we can understand that the LCM of 685,146,290,254 is 368336830.
