Find LCM of 695,285,506,712,780 with Prime Factorization
| 2 | 695, 285, 506, 712, 780 |
| 2 | 695, 285, 253, 356, 390 |
| 3 | 695, 285, 253, 178, 195 |
| 5 | 695, 95, 253, 178, 65 |
| 139, 19, 253, 178, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 139 x 19 x 253 x 178 x 13 = 92769139320
Therefore, the lowest common multiple of 695,285,506,712,780 is 92769139320.
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.
695 x 285 x 506 x 712 x 780 = 55661483592000
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.
695 : 1, 5, 139, 695
285 : 1, 3, 5, 15, 19, 57, 95, 285
506 : 1, 2, 11, 22, 23, 46, 253, 506
712 : 1, 2, 4, 8, 89, 178, 356, 712
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,285,506,712,780, is 1.
Now, the common factors can be found like this.
695:5x 139
285:3x 5x 19
506:2x 11x 23
712:2x 2x 2x 89
780:2x 2x 3x 5x 13
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 5 = 600
Therefore, the value for common factors is 600.
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 = 55661483592000/(1x600)
LCM = 55661483592000/600
LCM = 92769139320
Thus, we can understand that the LCM of 695,285,506,712,780 is 92769139320.
