Find LCM of 720,492,320,944,802 with Prime Factorization
| 2 | 720, 492, 320, 944, 802 |
| 2 | 360, 246, 160, 472, 401 |
| 2 | 180, 123, 80, 236, 401 |
| 2 | 90, 123, 40, 118, 401 |
| 3 | 45, 123, 20, 59, 401 |
| 5 | 15, 41, 20, 59, 401 |
| 3, 41, 4, 59, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 3 x 41 x 4 x 59 x 401 = 2793654720
Therefore, the lowest common multiple of 720,492,320,944,802 is 2793654720.
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.
720 x 492 x 320 x 944 x 802 = 85821072998400
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
802 : 1, 2, 401, 802
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,492,320,944,802, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
492:2x 2x 3x 41
320:2x 2x 2x 2x 2x 2x 5
944:2x 2x 2x 2x 59
802:2x 401
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 2x 2x 2x 2x 2x 2x 3x 5 = 15360
Therefore, the value for common factors is 15360.
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 = 85821072998400/(2x15360)
LCM = 85821072998400/30720
LCM = 2793654720
Thus, we can understand that the LCM of 720,492,320,944,802 is 2793654720.
