Find LCM of 378,980,851,294,505 with Prime Factorization
| 2 | 378, 980, 851, 294, 505 |
| 3 | 189, 490, 851, 147, 505 |
| 5 | 63, 490, 851, 49, 505 |
| 7 | 63, 98, 851, 49, 101 |
| 7 | 9, 14, 851, 7, 101 |
| 9, 2, 851, 1, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 7 x 9 x 2 x 851 x 1 x 101 = 2274263460
Therefore, the lowest common multiple of 378,980,851,294,505 is 2274263460.
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.
378 x 980 x 851 x 294 x 505 = 46804342006800
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
851 : 1, 23, 37, 851
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,980,851,294,505, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
980:2x 2x 5x 7x 7
851:23x 37
294:2x 3x 7x 7
505:5x 101
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 5x 7x 7x 7 = 20580
Therefore, the value for common factors is 20580.
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 = 46804342006800/(1x20580)
LCM = 46804342006800/20580
LCM = 2274263460
Thus, we can understand that the LCM of 378,980,851,294,505 is 2274263460.
