Given numbers are 290,980,630,292

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

The LCM of 290,980,630,292 is 18671940.

Find LCM of 290,980,630,292 with Prime Factorization

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

2 x 2 x 5 x 7 x 29 x 7 x 9 x 73 = 18671940

Therefore, the lowest common multiple of 290,980,630,292 is 18671940.

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.

290 x 980 x 630 x 292 = 52281432000

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.

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

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

292 : 1, 2, 4, 73, 146, 292

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,980,630,292, is 2.

Now, the common factors can be found like this.

290:2x 5x 29

980:2x 2x 5x 7x 7

630:2x 3x 3x 5x 7

292:2x 2x 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 2x 5x 5x 7 = 1400

Therefore, the value for common factors is 1400.

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 = 52281432000/(2x1400)

LCM = 52281432000/2800

LCM = 18671940

Thus, we can understand that the LCM of 290,980,630,292 is 18671940.
