Find LCM of 962,949,861,285,938 with Prime Factorization
| 2 | 962, 949, 861, 285, 938 |
| 3 | 481, 949, 861, 285, 469 |
| 7 | 481, 949, 287, 95, 469 |
| 13 | 481, 949, 41, 95, 67 |
| 37, 73, 41, 95, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 37 x 73 x 41 x 95 x 67 = 384857089890
Therefore, the lowest common multiple of 962,949,861,285,938 is 384857089890.
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.
962 x 949 x 861 x 285 x 938 = 210131971079940
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.
962 : 1, 2, 13, 26, 37, 74, 481, 962
949 : 1, 13, 73, 949
861 : 1, 3, 7, 21, 41, 123, 287, 861
285 : 1, 3, 5, 15, 19, 57, 95, 285
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 962,949,861,285,938, is 1.
Now, the common factors can be found like this.
962:2x 13x 37
949:13x 73
861:3x 7x 41
285:3x 5x 19
938:2x 7x 67
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 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 210131971079940/(1x546)
LCM = 210131971079940/546
LCM = 384857089890
Thus, we can understand that the LCM of 962,949,861,285,938 is 384857089890.
