HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 152, 528 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 665, 152, 528 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 665, 152, 528 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 665, 152, 528 is 1.

HCF(665, 152, 528) = 1

HCF of 665, 152, 528 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 665, 152, 528 is 1.

Highest Common Factor of 665,152,528 using Euclid's algorithm

Highest Common Factor of 665,152,528 is 1

Step 1: Since 665 > 152, we apply the division lemma to 665 and 152, to get

665 = 152 x 4 + 57

Step 2: Since the reminder 152 ≠ 0, we apply division lemma to 57 and 152, to get

152 = 57 x 2 + 38

Step 3: We consider the new divisor 57 and the new remainder 38, and apply the division lemma to get

57 = 38 x 1 + 19

We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get

38 = 19 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 665 and 152 is 19

Notice that 19 = HCF(38,19) = HCF(57,38) = HCF(152,57) = HCF(665,152) .

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

Step 1: Since 528 > 19, we apply the division lemma to 528 and 19, to get

528 = 19 x 27 + 15

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 15 and 19, to get

19 = 15 x 1 + 4

Step 3: We consider the new divisor 15 and the new remainder 4, and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 528 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(528,19) .
