Find LCM of 136,988,646,370,946 with Prime Factorization
2 | 136, 988, 646, 370, 946 |
2 | 68, 494, 323, 185, 473 |
17 | 34, 247, 323, 185, 473 |
19 | 2, 247, 19, 185, 473 |
2, 13, 1, 185, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 2 x 13 x 1 x 185 x 473 = 2939467960
Therefore, the lowest common multiple of 136,988,646,370,946 is 2939467960.
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.
136 x 988 x 646 x 370 x 946 = 30382340834560
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
646 : 1, 2, 17, 19, 34, 38, 323, 646
370 : 1, 2, 5, 10, 37, 74, 185, 370
946 : 1, 2, 11, 22, 43, 86, 473, 946
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,988,646,370,946, is 2.
Now, the common factors can be found like this.
136:2x 2x 2x 17
988:2x 2x 13x 19
646:2x 17x 19
370:2x 5x 37
946:2x 11x 43
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 2x 2x 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 30382340834560/(2x5168)
LCM = 30382340834560/10336
LCM = 2939467960
Thus, we can understand that the LCM of 136,988,646,370,946 is 2939467960.
