HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 208, 970, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 208, 970, 437 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 208, 970, 437 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 208, 970, 437 is 1.

HCF(208, 970, 437) = 1

HCF of 208, 970, 437 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 208, 970, 437 is 1.

Highest Common Factor of 208,970,437 using Euclid's algorithm

Highest Common Factor of 208,970,437 is 1

Step 1: Since 970 > 208, we apply the division lemma to 970 and 208, to get

970 = 208 x 4 + 138

Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 138 and 208, to get

208 = 138 x 1 + 70

Step 3: We consider the new divisor 138 and the new remainder 70, and apply the division lemma to get

138 = 70 x 1 + 68

We consider the new divisor 70 and the new remainder 68,and apply the division lemma to get

70 = 68 x 1 + 2

We consider the new divisor 68 and the new remainder 2,and apply the division lemma to get

68 = 2 x 34 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 208 and 970 is 2

Notice that 2 = HCF(68,2) = HCF(70,68) = HCF(138,70) = HCF(208,138) = HCF(970,208) .

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

Step 1: Since 437 > 2, we apply the division lemma to 437 and 2, to get

437 = 2 x 218 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 437 is 1

Notice that 1 = HCF(2,1) = HCF(437,2) .
