Find LCM of 435,785,728,210 with Prime Factorization


2 435, 785, 728, 210
3 435, 785, 364, 105
5 145, 785, 364, 35
7 29, 157, 364, 7
29, 157, 52, 1

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

2 x 3 x 5 x 7 x 29 x 157 x 52 x 1 = 49718760

Therefore, the lowest common multiple of 435,785,728,210 is 49718760.

LCM Formula to Find Lowest Common Multiple of 435,785,728,210

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.

435 x 785 x 728 x 210 = 52204698000

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.

435 : 1, 3, 5, 15, 29, 87, 145, 435

785 : 1, 5, 157, 785

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 435,785,728,210, is 1.

Now, the common factors can be found like this.

435:3x 5x 29

785:5x 157

728:2x 2x 2x 7x 13

210:2x 3x 5x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 5x 5x 7 = 1050

Therefore, the value for common factors is 1050.

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 = 52204698000/(1x1050)

LCM = 52204698000/1050

LCM = 49718760

Thus, we can understand that the LCM of 435,785,728,210 is 49718760.
