Find LCM of 288,639,931,862,679 with Prime Factorization
| 2 | 288, 639, 931, 862, 679 |
| 3 | 144, 639, 931, 431, 679 |
| 3 | 48, 213, 931, 431, 679 |
| 7 | 16, 71, 931, 431, 679 |
| 16, 71, 133, 431, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 16 x 71 x 133 x 431 x 97 = 795883538016
Therefore, the lowest common multiple of 288,639,931,862,679 is 795883538016.
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.
288 x 639 x 931 x 862 x 679 = 100281325790016
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
639 : 1, 3, 9, 71, 213, 639
931 : 1, 7, 19, 49, 133, 931
862 : 1, 2, 431, 862
679 : 1, 7, 97, 679
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,639,931,862,679, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
639:3x 3x 71
931:7x 7x 19
862:2x 431
679:7x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 100281325790016/(1x126)
LCM = 100281325790016/126
LCM = 795883538016
Thus, we can understand that the LCM of 288,639,931,862,679 is 795883538016.
