Find LCM of 938,616,921,628,670 with Prime Factorization
| 2 | 938, 616, 921, 628, 670 |
| 2 | 469, 308, 921, 314, 335 |
| 7 | 469, 154, 921, 157, 335 |
| 67 | 67, 22, 921, 157, 335 |
| 1, 22, 921, 157, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 67 x 1 x 22 x 921 x 157 x 5 = 29839036920
Therefore, the lowest common multiple of 938,616,921,628,670 is 29839036920.
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.
938 x 616 x 921 x 628 x 670 = 223912133047680
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.
938 : 1, 2, 7, 14, 67, 134, 469, 938
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
921 : 1, 3, 307, 921
628 : 1, 2, 4, 157, 314, 628
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,616,921,628,670, is 1.
Now, the common factors can be found like this.
938:2x 7x 67
616:2x 2x 2x 7x 11
921:3x 307
628:2x 2x 157
670:2x 5x 67
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 7x 67 = 7504
Therefore, the value for common factors is 7504.
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 = 223912133047680/(1x7504)
LCM = 223912133047680/7504
LCM = 29839036920
Thus, we can understand that the LCM of 938,616,921,628,670 is 29839036920.
