HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 285, 803, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 970, 285, 803, 487 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 970, 285, 803, 487 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 970, 285, 803, 487 is 1.

HCF(970, 285, 803, 487) = 1

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

HCF of:

Highest common factor (HCF) of 970, 285, 803, 487 is 1.

Highest Common Factor of 970,285,803,487 using Euclid's algorithm

Highest Common Factor of 970,285,803,487 is 1

Step 1: Since 970 > 285, we apply the division lemma to 970 and 285, to get

970 = 285 x 3 + 115

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 115 and 285, to get

285 = 115 x 2 + 55

Step 3: We consider the new divisor 115 and the new remainder 55, and apply the division lemma to get

115 = 55 x 2 + 5

We consider the new divisor 55 and the new remainder 5, and apply the division lemma to get

55 = 5 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 970 and 285 is 5

Notice that 5 = HCF(55,5) = HCF(115,55) = HCF(285,115) = HCF(970,285) .


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

Step 1: Since 803 > 5, we apply the division lemma to 803 and 5, to get

803 = 5 x 160 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 803 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(803,5) .


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

Step 1: Since 487 > 1, we apply the division lemma to 487 and 1, to get

487 = 1 x 487 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 487 is 1

Notice that 1 = HCF(487,1) .
