Given numbers are 781,250,678,784,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,250,678,784,765 is 1323265482000.
Find LCM of 781,250,678,784,765 with Prime Factorization
| 2 | 781, 250, 678, 784, 765 |
| 3 | 781, 125, 339, 392, 765 |
| 5 | 781, 125, 113, 392, 255 |
| 781, 25, 113, 392, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 781 x 25 x 113 x 392 x 51 = 1323265482000
Therefore, the lowest common multiple of 781,250,678,784,765 is 1323265482000.
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.
781 x 250 x 678 x 784 x 765 = 79395928920000
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.
781 : 1, 11, 71, 781
250 : 1, 2, 5, 10, 25, 50, 125, 250
678 : 1, 2, 3, 6, 113, 226, 339, 678
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,250,678,784,765, is 1.
Now, the common factors can be found like this.
781:11x 71
250:2x 5x 5x 5
678:2x 3x 113
784:2x 2x 2x 2x 7x 7
765:3x 3x 5x 17
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 5 = 60
Therefore, the value for common factors is 60.
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 = 79395928920000/(1x60)
LCM = 79395928920000/60
LCM = 1323265482000
Thus, we can understand that the LCM of 781,250,678,784,765 is 1323265482000.
