The LCM of 690,966,953,798 is 87456810.
Find LCM of 690,966,953,798 with Prime Factorization
| 2 | 690, 966, 953, 798 |
| 3 | 345, 483, 953, 399 |
| 7 | 115, 161, 953, 133 |
| 23 | 115, 23, 953, 19 |
| 5, 1, 953, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 5 x 1 x 953 x 19 = 87456810
Therefore, the lowest common multiple of 690,966,953,798 is 87456810.
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.
690 x 966 x 953 x 798 = 506899670760
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
953 : 1, 953
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,966,953,798, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
966:2x 3x 7x 23
953:953
798:2x 3x 7x 19
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 3x 7x 23 = 5796
Therefore, the value for common factors is 5796.
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 = 506899670760/(1x5796)
LCM = 506899670760/5796
LCM = 87456810
Thus, we can understand that the LCM of 690,966,953,798 is 87456810.
