The LCM of 785,840,390,594 is 169729560.

Find LCM of 785,840,390,594 with Prime Factorization


2 785, 840, 390, 594
3 785, 420, 195, 297
5 785, 140, 65, 99
157, 28, 13, 99

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 157 x 28 x 13 x 99 = 169729560

Therefore, the lowest common multiple of 785,840,390,594 is 169729560.

LCM Formula to Find Lowest Common Multiple of 785,840,390,594

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.

785 x 840 x 390 x 594 = 152756604000

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.

785 : 1, 5, 157, 785

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,840,390,594, is 1.

Now, the common factors can be found like this.

785:5x 157

840:2x 2x 2x 3x 5x 7

390:2x 3x 5x 13

594:2x 3x 3x 3x 11

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 5x 5 = 900

Therefore, the value for common factors is 900.

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 = 152756604000/(1x900)

LCM = 152756604000/900

LCM = 169729560

Thus, we can understand that the LCM of 785,840,390,594 is 169729560.
