HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 248, 905, 89 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 248, 905, 89 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 248, 905, 89 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 248, 905, 89 is 1.

HCF(248, 905, 89) = 1

Highest common factor (HCF) of 248, 905, 89 is 1.

Highest Common Factor of 248,905,89 using Euclid's algorithm

Highest Common Factor of 248,905,89 is 1

Step 1: Since 905 > 248, we apply the division lemma to 905 and 248, to get

905 = 248 x 3 + 161

Step 2: Since the reminder 248 ≠ 0, we apply division lemma to 161 and 248, to get

248 = 161 x 1 + 87

Step 3: We consider the new divisor 161 and the new remainder 87, and apply the division lemma to get

161 = 87 x 1 + 74

We consider the new divisor 87 and the new remainder 74,and apply the division lemma to get

87 = 74 x 1 + 13

We consider the new divisor 74 and the new remainder 13,and apply the division lemma to get

74 = 13 x 5 + 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 248 and 905 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(74,13) = HCF(87,74) = HCF(161,87) = HCF(248,161) = HCF(905,248) .

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

Step 1: Since 89 > 1, we apply the division lemma to 89 and 1, to get

89 = 1 x 89 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 89 is 1

Notice that 1 = HCF(89,1) .
