Find LCM of 781,740,935,639,334 with Prime Factorization
| 2 | 781, 740, 935, 639, 334 |
| 5 | 781, 370, 935, 639, 167 |
| 11 | 781, 74, 187, 639, 167 |
| 71 | 71, 74, 17, 639, 167 |
| 1, 74, 17, 9, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 71 x 1 x 74 x 17 x 9 x 167 = 14766944940
Therefore, the lowest common multiple of 781,740,935,639,334 is 14766944940.
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 740 x 935 x 639 x 334 = 115329839981400
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
935 : 1, 5, 11, 17, 55, 85, 187, 935
639 : 1, 3, 9, 71, 213, 639
334 : 1, 2, 167, 334
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,740,935,639,334, is 1.
Now, the common factors can be found like this.
781:11x 71
740:2x 2x 5x 37
935:5x 11x 17
639:3x 3x 71
334:2x 167
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 11x 71 = 7810
Therefore, the value for common factors is 7810.
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 = 115329839981400/(1x7810)
LCM = 115329839981400/7810
LCM = 14766944940
Thus, we can understand that the LCM of 781,740,935,639,334 is 14766944940.
