Given numbers are 560,780,930,916,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 560,780,930,916,470 is 7286981520.
Find LCM of 560,780,930,916,470 with Prime Factorization
| 2 | 560, 780, 930, 916, 470 |
| 2 | 280, 390, 465, 458, 235 |
| 3 | 140, 195, 465, 229, 235 |
| 5 | 140, 65, 155, 229, 235 |
| 28, 13, 31, 229, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 28 x 13 x 31 x 229 x 47 = 7286981520
Therefore, the lowest common multiple of 560,780,930,916,470 is 7286981520.
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 930 x 916 x 470 = 174887556480000
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
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
916 : 1, 2, 4, 229, 458, 916
470 : 1, 2, 5, 10, 47, 94, 235, 470
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,780,930,916,470, is 2.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
780:2x 2x 3x 5x 13
930:2x 3x 5x 31
916:2x 2x 229
470:2x 5x 47
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 3x 5x 5x 5 = 12000
Therefore, the value for common factors is 12000.
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 = 174887556480000/(2x12000)
LCM = 174887556480000/24000
LCM = 7286981520
Thus, we can understand that the LCM of 560,780,930,916,470 is 7286981520.
