Given numbers are 724,270,781,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,270,781,630 is 534344580.
Find LCM of 724,270,781,630 with Prime Factorization
| 2 | 724, 270, 781, 630 |
| 3 | 362, 135, 781, 315 |
| 3 | 362, 45, 781, 105 |
| 5 | 362, 15, 781, 35 |
| 362, 3, 781, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 362 x 3 x 781 x 7 = 534344580
Therefore, the lowest common multiple of 724,270,781,630 is 534344580.
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.
724 x 270 x 781 x 630 = 96182024400
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.
724 : 1, 2, 4, 181, 362, 724
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
781 : 1, 11, 71, 781
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,270,781,630, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
270:2x 3x 3x 3x 5
781:11x 71
630:2x 3x 3x 5x 7
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 96182024400/(1x180)
LCM = 96182024400/180
LCM = 534344580
Thus, we can understand that the LCM of 724,270,781,630 is 534344580.
