The LCM of 833,139,350,490,781 is 4521482350.
Find LCM of 833,139,350,490,781 with Prime Factorization
| 2 | 833, 139, 350, 490, 781 |
| 5 | 833, 139, 175, 245, 781 |
| 7 | 833, 139, 35, 49, 781 |
| 7 | 119, 139, 5, 7, 781 |
| 17, 139, 5, 1, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 17 x 139 x 5 x 1 x 781 = 4521482350
Therefore, the lowest common multiple of 833,139,350,490,781 is 4521482350.
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.
833 x 139 x 350 x 490 x 781 = 15508684460500
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.
833 : 1, 7, 17, 49, 119, 833
139 : 1, 139
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,139,350,490,781, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
139:139
350:2x 5x 5x 7
490:2x 5x 7x 7
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7x 7 = 3430
Therefore, the value for common factors is 3430.
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 = 15508684460500/(1x3430)
LCM = 15508684460500/3430
LCM = 4521482350
Thus, we can understand that the LCM of 833,139,350,490,781 is 4521482350.
