Given numbers are 781,465,805,510,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,465,805,510,203 is 57650991090.
Find LCM of 781,465,805,510,203 with Prime Factorization
| 3 | 781, 465, 805, 510, 203 |
| 5 | 781, 155, 805, 170, 203 |
| 7 | 781, 31, 161, 34, 203 |
| 781, 31, 23, 34, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 781 x 31 x 23 x 34 x 29 = 57650991090
Therefore, the lowest common multiple of 781,465,805,510,203 is 57650991090.
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.
781 x 465 x 805 x 510 x 203 = 30266770322250
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.
781 : 1, 11, 71, 781
465 : 1, 3, 5, 15, 31, 93, 155, 465
805 : 1, 5, 7, 23, 35, 115, 161, 805
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,465,805,510,203, is 1.
Now, the common factors can be found like this.
781:11x 71
465:3x 5x 31
805:5x 7x 23
510:2x 3x 5x 17
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 30266770322250/(1x525)
LCM = 30266770322250/525
LCM = 57650991090
Thus, we can understand that the LCM of 781,465,805,510,203 is 57650991090.
