Find LCM of 570,946,786,172,430 with Prime Factorization
2 | 570, 946, 786, 172, 430 |
3 | 285, 473, 393, 86, 215 |
5 | 95, 473, 131, 86, 215 |
43 | 19, 473, 131, 86, 43 |
19, 11, 131, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 19 x 11 x 131 x 2 x 1 = 70637820
Therefore, the lowest common multiple of 570,946,786,172,430 is 70637820.
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.
570 x 946 x 786 x 172 x 430 = 31346239003200
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
946 : 1, 2, 11, 22, 43, 86, 473, 946
786 : 1, 2, 3, 6, 131, 262, 393, 786
172 : 1, 2, 4, 43, 86, 172
430 : 1, 2, 5, 10, 43, 86, 215, 430
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,946,786,172,430, is 2.
Now, the common factors can be found like this.
570:2x 3x 5x 19
946:2x 11x 43
786:2x 3x 131
172:2x 2x 43
430:2x 5x 43
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 43x 43 = 221880
Therefore, the value for common factors is 221880.
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 = 31346239003200/(2x221880)
LCM = 31346239003200/443760
LCM = 70637820
Thus, we can understand that the LCM of 570,946,786,172,430 is 70637820.
