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

2 x 3 x 3 x 5 x 19 x 48 x 7 x 961 = 552152160

Therefore, the lowest common multiple of 285,864,630,961 is 552152160.

LCM Formula to Find Lowest Common Multiple of 285,864,630,961

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.

285 x 864 x 630 x 961 = 149081083200

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,864,630,961, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

864:2x 2x 2x 2x 2x 3x 3x 3

630:2x 3x 3x 5x 7

961:31x 31

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 3x 3x 5 = 270

Therefore, the value for common factors is 270.

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 = 149081083200/(1x270)

LCM = 149081083200/270

LCM = 552152160

Thus, we can understand that the LCM of 285,864,630,961 is 552152160.
