Given numbers are 556,430,840,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,430,840,693 is 165682440.
Find LCM of 556,430,840,693 with Prime Factorization
| 2 | 556, 430, 840, 693 |
| 2 | 278, 215, 420, 693 |
| 3 | 139, 215, 210, 693 |
| 5 | 139, 215, 70, 231 |
| 7 | 139, 43, 14, 231 |
| 139, 43, 2, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 139 x 43 x 2 x 33 = 165682440
Therefore, the lowest common multiple of 556,430,840,693 is 165682440.
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.
556 x 430 x 840 x 693 = 139173249600
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.
556 : 1, 2, 4, 139, 278, 556
430 : 1, 2, 5, 10, 43, 86, 215, 430
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,430,840,693, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
430:2x 5x 43
840:2x 2x 2x 3x 5x 7
693:3x 3x 7x 11
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 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 139173249600/(1x840)
LCM = 139173249600/840
LCM = 165682440
Thus, we can understand that the LCM of 556,430,840,693 is 165682440.
