HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7128, 7623, 34929 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 7128, 7623, 34929 is 9 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 7128, 7623, 34929 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 7128, 7623, 34929 is 9.

HCF(7128, 7623, 34929) = 9

HCF of 7128, 7623, 34929 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 7128, 7623, 34929 is 9.

Highest Common Factor of 7128,7623,34929 using Euclid's algorithm

Highest Common Factor of 7128,7623,34929 is 9

Step 1: Since 7623 > 7128, we apply the division lemma to 7623 and 7128, to get

7623 = 7128 x 1 + 495

Step 2: Since the reminder 7128 ≠ 0, we apply division lemma to 495 and 7128, to get

7128 = 495 x 14 + 198

Step 3: We consider the new divisor 495 and the new remainder 198, and apply the division lemma to get

495 = 198 x 2 + 99

We consider the new divisor 198 and the new remainder 99, and apply the division lemma to get

198 = 99 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 99, the HCF of 7128 and 7623 is 99

Notice that 99 = HCF(198,99) = HCF(495,198) = HCF(7128,495) = HCF(7623,7128) .


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

Step 1: Since 34929 > 99, we apply the division lemma to 34929 and 99, to get

34929 = 99 x 352 + 81

Step 2: Since the reminder 99 ≠ 0, we apply division lemma to 81 and 99, to get

99 = 81 x 1 + 18

Step 3: We consider the new divisor 81 and the new remainder 18, and apply the division lemma to get

81 = 18 x 4 + 9

We consider the new divisor 18 and the new remainder 9, and apply the division lemma to get

18 = 9 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 99 and 34929 is 9

Notice that 9 = HCF(18,9) = HCF(81,18) = HCF(99,81) = HCF(34929,99) .
