Find LCM of 987,321,784,981,944 with Prime Factorization
| 2 | 987, 321, 784, 981, 944 |
| 2 | 987, 321, 392, 981, 472 |
| 2 | 987, 321, 196, 981, 236 |
| 2 | 987, 321, 98, 981, 118 |
| 3 | 987, 321, 49, 981, 59 |
| 7 | 329, 107, 49, 327, 59 |
| 47, 107, 7, 327, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 47 x 107 x 7 x 327 x 59 = 228201616944
Therefore, the lowest common multiple of 987,321,784,981,944 is 228201616944.
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.
987 x 321 x 784 x 981 x 944 = 230027229879552
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
321 : 1, 3, 107, 321
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
981 : 1, 3, 9, 109, 327, 981
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,321,784,981,944, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
321:3x 107
784:2x 2x 2x 2x 7x 7
981:3x 3x 109
944:2x 2x 2x 2x 59
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 2x 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 230027229879552/(1x1008)
LCM = 230027229879552/1008
LCM = 228201616944
Thus, we can understand that the LCM of 987,321,784,981,944 is 228201616944.
