Given numbers are 803,785,692,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,785,692,438 is 1308616980.
Find LCM of 803,785,692,438 with Prime Factorization
2 | 803, 785, 692, 438 |
73 | 803, 785, 346, 219 |
11, 785, 346, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 73 x 11 x 785 x 346 x 3 = 1308616980
Therefore, the lowest common multiple of 803,785,692,438 is 1308616980.
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.
803 x 785 x 692 x 438 = 191058079080
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.
803 : 1, 11, 73, 803
785 : 1, 5, 157, 785
692 : 1, 2, 4, 173, 346, 692
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,785,692,438, is 1.
Now, the common factors can be found like this.
803:11x 73
785:5x 157
692:2x 2x 173
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 73 = 146
Therefore, the value for common factors is 146.
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 = 191058079080/(1x146)
LCM = 191058079080/146
LCM = 1308616980
Thus, we can understand that the LCM of 803,785,692,438 is 1308616980.
