Find LCM of 440,380,722,438,390 with Prime Factorization


2 440, 380, 722, 438, 390
2 220, 190, 361, 219, 195
3 110, 95, 361, 219, 195
5 110, 95, 361, 73, 65
19 22, 19, 361, 73, 13
22, 1, 19, 73, 13

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

2 x 2 x 3 x 5 x 19 x 22 x 1 x 19 x 73 x 13 = 452217480

LCM Formula to Find Lowest Common Multiple of 440,380,722,438,390

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.

440 x 380 x 722 x 438 x 390 = 20621117088000

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.

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

722 : 1, 2, 19, 38, 361, 722

438 : 1, 2, 3, 6, 73, 146, 219, 438

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,380,722,438,390, is 2.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

380:2x 2x 5x 19

722:2x 19x 19

438:2x 3x 73

390:2x 3x 5x 13

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 2x 3x 5x 5x 19 = 22800

Therefore, the value for common factors is 22800.

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 = 20621117088000/(2x22800)

LCM = 20621117088000/45600

LCM = 452217480

Thus, we can understand that the LCM of 440,380,722,438,390 is 452217480.
