Find LCM of 924,209,370,720 with Prime Factorization
| 2 | 924, 209, 370, 720 |
| 2 | 462, 209, 185, 360 |
| 3 | 231, 209, 185, 180 |
| 5 | 77, 209, 185, 60 |
| 11 | 77, 209, 37, 12 |
| 7, 19, 37, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 7 x 19 x 37 x 12 = 38974320
Therefore, the lowest common multiple of 924,209,370,720 is 38974320.
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.
924 x 209 x 370 x 720 = 51446102400
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
209 : 1, 11, 19, 209
370 : 1, 2, 5, 10, 37, 74, 185, 370
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,209,370,720, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
209:11x 19
370:2x 5x 37
720:2x 2x 2x 2x 3x 3x 5
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 51446102400/(1x1320)
LCM = 51446102400/1320
LCM = 38974320
Thus, we can understand that the LCM of 924,209,370,720 is 38974320.
