Find LCM of 915,723,436,690,700 with Prime Factorization
| 2 | 915, 723, 436, 690, 700 |
| 2 | 915, 723, 218, 345, 350 |
| 3 | 915, 723, 109, 345, 175 |
| 5 | 305, 241, 109, 115, 175 |
| 61, 241, 109, 23, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 61 x 241 x 109 x 23 x 35 = 77396354700
Therefore, the lowest common multiple of 915,723,436,690,700 is 77396354700.
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.
915 x 723 x 436 x 690 x 700 = 139313438460000
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
723 : 1, 3, 241, 723
436 : 1, 2, 4, 109, 218, 436
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,723,436,690,700, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
723:3x 241
436:2x 2x 109
690:2x 3x 5x 23
700:2x 2x 5x 5x 7
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 3x 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 139313438460000/(1x1800)
LCM = 139313438460000/1800
LCM = 77396354700
Thus, we can understand that the LCM of 915,723,436,690,700 is 77396354700.
