The LCM of 784,730,365,901,918 is 6961414320.
Find LCM of 784,730,365,901,918 with Prime Factorization
| 2 | 784, 730, 365, 901, 918 |
| 5 | 392, 365, 365, 901, 459 |
| 17 | 392, 73, 73, 901, 459 |
| 73 | 392, 73, 73, 53, 27 |
| 392, 1, 1, 53, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 73 x 392 x 1 x 1 x 53 x 27 = 6961414320
Therefore, the lowest common multiple of 784,730,365,901,918 is 6961414320.
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 730 x 365 x 901 x 918 = 172782303422400
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
730 : 1, 2, 5, 10, 73, 146, 365, 730
365 : 1, 5, 73, 365
901 : 1, 17, 53, 901
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,730,365,901,918, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
730:2x 5x 73
365:5x 73
901:17x 53
918:2x 3x 3x 3x 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 5x 17x 73 = 24820
Therefore, the value for common factors is 24820.
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 = 172782303422400/(1x24820)
LCM = 172782303422400/24820
LCM = 6961414320
Thus, we can understand that the LCM of 784,730,365,901,918 is 6961414320.
