Given numbers are 685,570,572,619,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,570,572,619,871 is 926247199020.
Find LCM of 685,570,572,619,871 with Prime Factorization
| 2 | 685, 570, 572, 619, 871 |
| 5 | 685, 285, 286, 619, 871 |
| 13 | 137, 57, 286, 619, 871 |
| 137, 57, 22, 619, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 137 x 57 x 22 x 619 x 67 = 926247199020
Therefore, the lowest common multiple of 685,570,572,619,871 is 926247199020.
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.
685 x 570 x 572 x 619 x 871 = 120412135872600
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.
685 : 1, 5, 137, 685
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
619 : 1, 619
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,570,572,619,871, is 1.
Now, the common factors can be found like this.
685:5x 137
570:2x 3x 5x 19
572:2x 2x 11x 13
619:619
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 120412135872600/(1x130)
LCM = 120412135872600/130
LCM = 926247199020
Thus, we can understand that the LCM of 685,570,572,619,871 is 926247199020.
