HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 324, 764 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 147, 324, 764 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 147, 324, 764 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 147, 324, 764 is 1.

HCF(147, 324, 764) = 1

HCF of 147, 324, 764 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 147, 324, 764 is 1.

Highest Common Factor of 147,324,764 using Euclid's algorithm

Highest Common Factor of 147,324,764 is 1

Step 1: Since 324 > 147, we apply the division lemma to 324 and 147, to get

324 = 147 x 2 + 30

Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 30 and 147, to get

147 = 30 x 4 + 27

Step 3: We consider the new divisor 30 and the new remainder 27, and apply the division lemma to get

30 = 27 x 1 + 3

We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get

27 = 3 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 147 and 324 is 3

Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(147,30) = HCF(324,147) .

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

Step 1: Since 764 > 3, we apply the division lemma to 764 and 3, to get

764 = 3 x 254 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 764 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(764,3) .
