HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 6505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 398, 6505 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, 6505 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, 6505 is 1.

HCF(398, 6505) = 1

Highest common factor (HCF) of 398, 6505 is 1.

Highest Common Factor of 398,6505 using Euclid's algorithm

Highest Common Factor of 398,6505 is 1

Step 1: Since 6505 > 398, we apply the division lemma to 6505 and 398, to get

6505 = 398 x 16 + 137

Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 137 and 398, to get

398 = 137 x 2 + 124

Step 3: We consider the new divisor 137 and the new remainder 124, and apply the division lemma to get

137 = 124 x 1 + 13

We consider the new divisor 124 and the new remainder 13,and apply the division lemma to get

124 = 13 x 9 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 6505 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(124,13) = HCF(137,124) = HCF(398,137) = HCF(6505,398) .
