HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 996, 550 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 215, 996, 550 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 215, 996, 550 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 215, 996, 550 is 1.

HCF(215, 996, 550) = 1

HCF of 215, 996, 550 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 215, 996, 550 is 1.

Highest Common Factor of 215,996,550 using Euclid's algorithm

Highest Common Factor of 215,996,550 is 1

Step 1: Since 996 > 215, we apply the division lemma to 996 and 215, to get

996 = 215 x 4 + 136

Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 136 and 215, to get

215 = 136 x 1 + 79

Step 3: We consider the new divisor 136 and the new remainder 79, and apply the division lemma to get

136 = 79 x 1 + 57

We consider the new divisor 79 and the new remainder 57,and apply the division lemma to get

79 = 57 x 1 + 22

We consider the new divisor 57 and the new remainder 22,and apply the division lemma to get

57 = 22 x 2 + 13

We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get

22 = 13 x 1 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 215 and 996 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(57,22) = HCF(79,57) = HCF(136,79) = HCF(215,136) = HCF(996,215) .

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

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

550 = 1 x 550 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 550 is 1

Notice that 1 = HCF(550,1) .
