Find LCM of 560,780,702,912 with Prime Factorization
2 | 560, 780, 702, 912 |
2 | 280, 390, 351, 456 |
2 | 140, 195, 351, 228 |
2 | 70, 195, 351, 114 |
3 | 35, 195, 351, 57 |
5 | 35, 65, 117, 19 |
13 | 7, 13, 117, 19 |
7, 1, 9, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 13 x 7 x 1 x 9 x 19 = 3734640
Therefore, the lowest common multiple of 560,780,702,912 is 3734640.
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.
560 x 780 x 702 x 912 = 279649843200
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,780,702,912, is 2.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
780:2x 2x 3x 5x 13
702:2x 3x 3x 3x 13
912:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 3x 3x 5x 13 = 37440
Therefore, the value for common factors is 37440.
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 = 279649843200/(2x37440)
LCM = 279649843200/74880
LCM = 3734640
Thus, we can understand that the LCM of 560,780,702,912 is 3734640.
