HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7740, 3205 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 7740, 3205 is 5 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 7740, 3205 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 7740, 3205 is 5.

HCF(7740, 3205) = 5

Highest common factor (HCF) of 7740, 3205 is 5.

Highest Common Factor of 7740,3205 using Euclid's algorithm

Highest Common Factor of 7740,3205 is 5

Step 1: Since 7740 > 3205, we apply the division lemma to 7740 and 3205, to get

7740 = 3205 x 2 + 1330

Step 2: Since the reminder 3205 ≠ 0, we apply division lemma to 1330 and 3205, to get

3205 = 1330 x 2 + 545

Step 3: We consider the new divisor 1330 and the new remainder 545, and apply the division lemma to get

1330 = 545 x 2 + 240

We consider the new divisor 545 and the new remainder 240,and apply the division lemma to get

545 = 240 x 2 + 65

We consider the new divisor 240 and the new remainder 65,and apply the division lemma to get

240 = 65 x 3 + 45

We consider the new divisor 65 and the new remainder 45,and apply the division lemma to get

65 = 45 x 1 + 20

We consider the new divisor 45 and the new remainder 20,and apply the division lemma to get

45 = 20 x 2 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 7740 and 3205 is 5

Notice that 5 = HCF(20,5) = HCF(45,20) = HCF(65,45) = HCF(240,65) = HCF(545,240) = HCF(1330,545) = HCF(3205,1330) = HCF(7740,3205) .
