Find LCM of 974,471,620,452,915 with Prime Factorization
| 2 | 974, 471, 620, 452, 915 |
| 2 | 487, 471, 310, 226, 915 |
| 3 | 487, 471, 155, 113, 915 |
| 5 | 487, 157, 155, 113, 305 |
| 487, 157, 31, 113, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 487 x 157 x 31 x 113 x 61 = 980279309820
Therefore, the lowest common multiple of 974,471,620,452,915 is 980279309820.
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.
974 x 471 x 620 x 452 x 915 = 117633517178400
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.
974 : 1, 2, 487, 974
471 : 1, 3, 157, 471
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
452 : 1, 2, 4, 113, 226, 452
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,471,620,452,915, is 1.
Now, the common factors can be found like this.
974:2x 487
471:3x 157
620:2x 2x 5x 31
452:2x 2x 113
915:3x 5x 61
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 117633517178400/(1x120)
LCM = 117633517178400/120
LCM = 980279309820
Thus, we can understand that the LCM of 974,471,620,452,915 is 980279309820.
