The LCM of 781,551,255,700 is 15362816700.

Find LCM of 781,551,255,700 with Prime Factorization


5 781, 551, 255, 700
781, 551, 51, 140

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

5 x 781 x 551 x 51 x 140 = 15362816700

Therefore, the lowest common multiple of 781,551,255,700 is 15362816700.

LCM Formula to Find Lowest Common Multiple of 781,551,255,700

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.

781 x 551 x 255 x 700 = 76814083500

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.

781 : 1, 11, 71, 781

551 : 1, 19, 29, 551

255 : 1, 3, 5, 15, 17, 51, 85, 255

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,551,255,700, is 1.

Now, the common factors can be found like this.

781:11x 71

551:19x 29

255:3x 5x 17

700:2x 2x 5x 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.

5 = 5

Therefore, the value for common factors is 5.

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 = 76814083500/(1x5)

LCM = 76814083500/5

LCM = 15362816700

Thus, we can understand that the LCM of 781,551,255,700 is 15362816700.
