Find LCM of 712,877,350,840 with Prime Factorization
| 2 | 712, 877, 350, 840 |
| 2 | 356, 877, 175, 420 |
| 2 | 178, 877, 175, 210 |
| 5 | 89, 877, 175, 105 |
| 7 | 89, 877, 35, 21 |
| 89, 877, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 89 x 877 x 5 x 3 = 327822600
Therefore, the lowest common multiple of 712,877,350,840 is 327822600.
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.
712 x 877 x 350 x 840 = 183580656000
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
877 : 1, 877
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,877,350,840, is 1.
Now, the common factors can be found like this.
712:2x 2x 2x 89
877:877
350:2x 5x 5x 7
840:2x 2x 2x 3x 5x 7
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 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 183580656000/(1x560)
LCM = 183580656000/560
LCM = 327822600
Thus, we can understand that the LCM of 712,877,350,840 is 327822600.
