Given numbers are 270,781,453,955,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 270,781,453,955,690 is 139879138410.
Find LCM of 270,781,453,955,690 with Prime Factorization
| 2 | 270, 781, 453, 955, 690 |
| 3 | 135, 781, 453, 955, 345 |
| 5 | 45, 781, 151, 955, 115 |
| 9, 781, 151, 191, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 9 x 781 x 151 x 191 x 23 = 139879138410
Therefore, the lowest common multiple of 270,781,453,955,690 is 139879138410.
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.
270 x 781 x 453 x 955 x 690 = 62945612284500
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
781 : 1, 11, 71, 781
453 : 1, 3, 151, 453
955 : 1, 5, 191, 955
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,781,453,955,690, is 1.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
781:11x 71
453:3x 151
955:5x 191
690:2x 3x 5x 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 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 62945612284500/(1x450)
LCM = 62945612284500/450
LCM = 139879138410
Thus, we can understand that the LCM of 270,781,453,955,690 is 139879138410.
