HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 286, 797, 780, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 286, 797, 780, 763 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 286, 797, 780, 763 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 286, 797, 780, 763 is 1.

HCF(286, 797, 780, 763) = 1

Highest Common Factor of 286,797,780,763 using Euclid's algorithm

Highest Common Factor of 286,797,780,763 is 1

Step 1: Since 797 > 286, we apply the division lemma to 797 and 286, to get

797 = 286 x 2 + 225

Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 225 and 286, to get

286 = 225 x 1 + 61

Step 3: We consider the new divisor 225 and the new remainder 61, and apply the division lemma to get

225 = 61 x 3 + 42

We consider the new divisor 61 and the new remainder 42,and apply the division lemma to get

61 = 42 x 1 + 19

We consider the new divisor 42 and the new remainder 19,and apply the division lemma to get

42 = 19 x 2 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 286 and 797 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(42,19) = HCF(61,42) = HCF(225,61) = HCF(286,225) = HCF(797,286) .

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

Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get

780 = 1 x 780 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1

Notice that 1 = HCF(780,1) .

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

Step 1: Since 763 > 1, we apply the division lemma to 763 and 1, to get

763 = 1 x 763 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 763 is 1

Notice that 1 = HCF(763,1) .
