HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 865, 614, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 842, 865, 614, 305 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 842, 865, 614, 305 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 842, 865, 614, 305 is 1.

HCF(842, 865, 614, 305) = 1

Highest Common Factor of 842,865,614,305 using Euclid's algorithm

Highest Common Factor of 842,865,614,305 is 1

Step 1: Since 865 > 842, we apply the division lemma to 865 and 842, to get

865 = 842 x 1 + 23

Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 23 and 842, to get

842 = 23 x 36 + 14

Step 3: We consider the new divisor 23 and the new remainder 14, and apply the division lemma to get

23 = 14 x 1 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 842 and 865 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(23,14) = HCF(842,23) = HCF(865,842) .

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

Step 1: Since 614 > 1, we apply the division lemma to 614 and 1, to get

614 = 1 x 614 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 614 is 1

Notice that 1 = HCF(614,1) .

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

Step 1: Since 305 > 1, we apply the division lemma to 305 and 1, to get

305 = 1 x 305 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 305 is 1

Notice that 1 = HCF(305,1) .
