Find LCM of 698,350,210,755,520 with Prime Factorization
2 | 698, 350, 210, 755, 520 |
5 | 349, 175, 105, 755, 260 |
7 | 349, 35, 21, 151, 52 |
349, 5, 3, 151, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 349 x 5 x 3 x 151 x 52 = 2877365400
Therefore, the lowest common multiple of 698,350,210,755,520 is 2877365400.
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.
698 x 350 x 210 x 755 x 520 = 20141557800000
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.
698 : 1, 2, 349, 698
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
755 : 1, 5, 151, 755
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,350,210,755,520, is 1.
Now, the common factors can be found like this.
698:2x 349
350:2x 5x 5x 7
210:2x 3x 5x 7
755:5x 151
520:2x 2x 2x 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 2x 5x 5x 5x 7 = 7000
Therefore, the value for common factors is 7000.
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 = 20141557800000/(1x7000)
LCM = 20141557800000/7000
LCM = 2877365400
Thus, we can understand that the LCM of 698,350,210,755,520 is 2877365400.
