HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 891, 831 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 550, 891, 831 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 550, 891, 831 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 550, 891, 831 is 1.

HCF(550, 891, 831) = 1

Highest common factor (HCF) of 550, 891, 831 is 1.

Highest Common Factor of 550,891,831 using Euclid's algorithm

Highest Common Factor of 550,891,831 is 1

Step 1: Since 891 > 550, we apply the division lemma to 891 and 550, to get

891 = 550 x 1 + 341

Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 341 and 550, to get

550 = 341 x 1 + 209

Step 3: We consider the new divisor 341 and the new remainder 209, and apply the division lemma to get

341 = 209 x 1 + 132

We consider the new divisor 209 and the new remainder 132,and apply the division lemma to get

209 = 132 x 1 + 77

We consider the new divisor 132 and the new remainder 77,and apply the division lemma to get

132 = 77 x 1 + 55

We consider the new divisor 77 and the new remainder 55,and apply the division lemma to get

77 = 55 x 1 + 22

We consider the new divisor 55 and the new remainder 22,and apply the division lemma to get

55 = 22 x 2 + 11

We consider the new divisor 22 and the new remainder 11,and apply the division lemma to get

22 = 11 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 550 and 891 is 11

Notice that 11 = HCF(22,11) = HCF(55,22) = HCF(77,55) = HCF(132,77) = HCF(209,132) = HCF(341,209) = HCF(550,341) = HCF(891,550) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 831 > 11, we apply the division lemma to 831 and 11, to get

831 = 11 x 75 + 6

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get

11 = 6 x 1 + 5

Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 831 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(831,11) .
