The LCM of 947,992,714,533,221 is 178754538144.
Find LCM of 947,992,714,533,221 with Prime Factorization
| 2 | 947, 992, 714, 533, 221 |
| 13 | 947, 496, 357, 533, 221 |
| 17 | 947, 496, 357, 41, 17 |
| 947, 496, 21, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 947 x 496 x 21 x 41 x 1 = 178754538144
Therefore, the lowest common multiple of 947,992,714,533,221 is 178754538144.
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.
947 x 992 x 714 x 533 x 221 = 79009505859648
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.
947 : 1, 947
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
533 : 1, 13, 41, 533
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,992,714,533,221, is 1.
Now, the common factors can be found like this.
947:947
992:2x 2x 2x 2x 2x 31
714:2x 3x 7x 17
533:13x 41
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 79009505859648/(1x442)
LCM = 79009505859648/442
LCM = 178754538144
Thus, we can understand that the LCM of 947,992,714,533,221 is 178754538144.
