Given numbers are 485,399,684,762,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 485,399,684,762,640 is 9437339520.
Find LCM of 485,399,684,762,640 with Prime Factorization
| 2 | 485, 399, 684, 762, 640 |
| 2 | 485, 399, 342, 381, 320 |
| 3 | 485, 399, 171, 381, 160 |
| 5 | 485, 133, 57, 127, 160 |
| 19 | 97, 133, 57, 127, 32 |
| 97, 7, 3, 127, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 97 x 7 x 3 x 127 x 32 = 9437339520
Therefore, the lowest common multiple of 485,399,684,762,640 is 9437339520.
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.
485 x 399 x 684 x 762 x 640 = 64551402316800
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.
485 : 1, 5, 97, 485
399 : 1, 3, 7, 19, 21, 57, 133, 399
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
762 : 1, 2, 3, 6, 127, 254, 381, 762
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,399,684,762,640, is 1.
Now, the common factors can be found like this.
485:5x 97
399:3x 7x 19
684:2x 2x 3x 3x 19
762:2x 3x 127
640:2x 2x 2x 2x 2x 2x 2x 5
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 3x 3x 5x 19 = 6840
Therefore, the value for common factors is 6840.
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 = 64551402316800/(1x6840)
LCM = 64551402316800/6840
LCM = 9437339520
Thus, we can understand that the LCM of 485,399,684,762,640 is 9437339520.
