Find LCM of 795,697,769,640,780 with Prime Factorization
| 2 | 795, 697, 769, 640, 780 |
| 2 | 795, 697, 769, 320, 390 |
| 3 | 795, 697, 769, 160, 195 |
| 5 | 265, 697, 769, 160, 65 |
| 53, 697, 769, 32, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 697 x 769 x 32 x 13 = 709054419840
Therefore, the lowest common multiple of 795,697,769,640,780 is 709054419840.
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.
795 x 697 x 769 x 640 x 780 = 212716325952000
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.
795 : 1, 3, 5, 15, 53, 159, 265, 795
697 : 1, 17, 41, 697
769 : 1, 769
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 795,697,769,640,780, is 1.
Now, the common factors can be found like this.
795:3x 5x 53
697:17x 41
769:769
640:2x 2x 2x 2x 2x 2x 2x 5
780:2x 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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 212716325952000/(1x300)
LCM = 212716325952000/300
LCM = 709054419840
Thus, we can understand that the LCM of 795,697,769,640,780 is 709054419840.
