HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 70663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 398, 70663 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 398, 70663 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 398, 70663 is 1.

HCF(398, 70663) = 1

HCF of 398, 70663 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 398, 70663 is 1.

Highest Common Factor of 398,70663 using Euclid's algorithm

Highest Common Factor of 398,70663 is 1

Step 1: Since 70663 > 398, we apply the division lemma to 70663 and 398, to get

70663 = 398 x 177 + 217

Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 217 and 398, to get

398 = 217 x 1 + 181

Step 3: We consider the new divisor 217 and the new remainder 181, and apply the division lemma to get

217 = 181 x 1 + 36

We consider the new divisor 181 and the new remainder 36,and apply the division lemma to get

181 = 36 x 5 + 1

We consider the new divisor 36 and the new remainder 1,and apply the division lemma to get

36 = 1 x 36 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 70663 is 1

Notice that 1 = HCF(36,1) = HCF(181,36) = HCF(217,181) = HCF(398,217) = HCF(70663,398) .
