Find LCM of 900,642,772,670,499 with Prime Factorization
2 | 900, 642, 772, 670, 499 |
2 | 450, 321, 386, 335, 499 |
3 | 225, 321, 193, 335, 499 |
5 | 75, 107, 193, 335, 499 |
15, 107, 193, 67, 499 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 15 x 107 x 193 x 67 x 499 = 621382394700
Therefore, the lowest common multiple of 900,642,772,670,499 is 621382394700.
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.
900 x 642 x 772 x 670 x 499 = 149131774728000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
642 : 1, 2, 3, 6, 107, 214, 321, 642
772 : 1, 2, 4, 193, 386, 772
670 : 1, 2, 5, 10, 67, 134, 335, 670
499 : 1, 499
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,642,772,670,499, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
642:2x 3x 107
772:2x 2x 193
670:2x 5x 67
499:499
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 5 = 240
Therefore, the value for common factors is 240.
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 = 149131774728000/(1x240)
LCM = 149131774728000/240
LCM = 621382394700
Thus, we can understand that the LCM of 900,642,772,670,499 is 621382394700.
