Find LCM of 147,336,403,780 with Prime Factorization
2 | 147, 336, 403, 780 |
2 | 147, 168, 403, 390 |
3 | 147, 84, 403, 195 |
7 | 49, 28, 403, 65 |
13 | 7, 4, 403, 65 |
7, 4, 31, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 7 x 4 x 31 x 5 = 4739280
Therefore, the lowest common multiple of 147,336,403,780 is 4739280.
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.
147 x 336 x 403 x 780 = 15525881280
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.
147 : 1, 3, 7, 21, 49, 147
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
403 : 1, 13, 31, 403
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 147,336,403,780, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
336:2x 2x 2x 2x 3x 7
403:13x 31
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 3x 3x 7x 13 = 3276
Therefore, the value for common factors is 3276.
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 = 15525881280/(1x3276)
LCM = 15525881280/3276
LCM = 4739280
Thus, we can understand that the LCM of 147,336,403,780 is 4739280.
