HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 249, 460, 940 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 249, 460, 940 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 249, 460, 940 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 249, 460, 940 is 1.

HCF(249, 460, 940) = 1

Highest common factor (HCF) of 249, 460, 940 is 1.

Highest Common Factor of 249,460,940 using Euclid's algorithm

Highest Common Factor of 249,460,940 is 1

Step 1: Since 460 > 249, we apply the division lemma to 460 and 249, to get

460 = 249 x 1 + 211

Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 211 and 249, to get

249 = 211 x 1 + 38

Step 3: We consider the new divisor 211 and the new remainder 38, and apply the division lemma to get

211 = 38 x 5 + 21

We consider the new divisor 38 and the new remainder 21,and apply the division lemma to get

38 = 21 x 1 + 17

We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get

21 = 17 x 1 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 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 249 and 460 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(38,21) = HCF(211,38) = HCF(249,211) = HCF(460,249) .

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

Step 1: Since 940 > 1, we apply the division lemma to 940 and 1, to get

940 = 1 x 940 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 940 is 1

Notice that 1 = HCF(940,1) .
