The LCM of 840,516,770,598 is 118798680.
Find LCM of 840,516,770,598 with Prime Factorization
| 2 | 840, 516, 770, 598 |
| 2 | 420, 258, 385, 299 |
| 3 | 210, 129, 385, 299 |
| 5 | 70, 43, 385, 299 |
| 7 | 14, 43, 77, 299 |
| 2, 43, 11, 299 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 2 x 43 x 11 x 299 = 118798680
Therefore, the lowest common multiple of 840,516,770,598 is 118798680.
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.
840 x 516 x 770 x 598 = 199581782400
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
598 : 1, 2, 13, 23, 26, 46, 299, 598
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,516,770,598, is 2.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
516:2x 2x 3x 43
770:2x 5x 7x 11
598:2x 13x 23
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 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 199581782400/(2x840)
LCM = 199581782400/1680
LCM = 118798680
Thus, we can understand that the LCM of 840,516,770,598 is 118798680.
