Find LCM of 784,795,420,825,771 with Prime Factorization
2 | 784, 795, 420, 825, 771 |
2 | 392, 795, 210, 825, 771 |
3 | 196, 795, 105, 825, 771 |
5 | 196, 265, 35, 275, 257 |
7 | 196, 53, 7, 55, 257 |
28, 53, 1, 55, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 28 x 53 x 1 x 55 x 257 = 8810062800
Therefore, the lowest common multiple of 784,795,420,825,771 is 8810062800.
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.
784 x 795 x 420 x 825 x 771 = 166510186920000
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
795 : 1, 3, 5, 15, 53, 159, 265, 795
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,795,420,825,771, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
795:3x 5x 53
420:2x 2x 3x 5x 7
825:3x 5x 5x 11
771:3x 257
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 3x 3x 3x 5x 5x 7 = 18900
Therefore, the value for common factors is 18900.
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 = 166510186920000/(1x18900)
LCM = 166510186920000/18900
LCM = 8810062800
Thus, we can understand that the LCM of 784,795,420,825,771 is 8810062800.
