Find LCM of 708,343,757,420,947 with Prime Factorization
| 2 | 708, 343, 757, 420, 947 |
| 2 | 354, 343, 757, 210, 947 |
| 3 | 177, 343, 757, 105, 947 |
| 7 | 59, 343, 757, 35, 947 |
| 59, 49, 757, 5, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 59 x 49 x 757 x 5 x 947 = 870448819380
Therefore, the lowest common multiple of 708,343,757,420,947 is 870448819380.
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.
708 x 343 x 757 x 420 x 947 = 73117700827920
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
343 : 1, 7, 49, 343
757 : 1, 757
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,343,757,420,947, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
343:7x 7x 7
757:757
420:2x 2x 3x 5x 7
947:947
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 73117700827920/(1x84)
LCM = 73117700827920/84
LCM = 870448819380
Thus, we can understand that the LCM of 708,343,757,420,947 is 870448819380.
