Given numbers are 437,120,980,722,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,120,980,722,782 is 829967880.
Find LCM of 437,120,980,722,782 with Prime Factorization
| 2 | 437, 120, 980, 722, 782 |
| 2 | 437, 60, 490, 361, 391 |
| 5 | 437, 30, 245, 361, 391 |
| 19 | 437, 6, 49, 361, 391 |
| 23 | 23, 6, 49, 19, 391 |
| 1, 6, 49, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 23 x 1 x 6 x 49 x 19 x 17 = 829967880
Therefore, the lowest common multiple of 437,120,980,722,782 is 829967880.
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.
437 x 120 x 980 x 722 x 782 = 29015677084800
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.
437 : 1, 19, 23, 437
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
722 : 1, 2, 19, 38, 361, 722
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,120,980,722,782, is 1.
Now, the common factors can be found like this.
437:19x 23
120:2x 2x 2x 3x 5
980:2x 2x 5x 7x 7
722:2x 19x 19
782:2x 17x 23
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 5x 19x 23 = 34960
Therefore, the value for common factors is 34960.
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 = 29015677084800/(1x34960)
LCM = 29015677084800/34960
LCM = 829967880
Thus, we can understand that the LCM of 437,120,980,722,782 is 829967880.
