HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 564, 706, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 564, 706, 973 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 564, 706, 973 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 564, 706, 973 is 1.

HCF(564, 706, 973) = 1

HCF of 564, 706, 973 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 564, 706, 973 is 1.

Highest Common Factor of 564,706,973 using Euclid's algorithm

Highest Common Factor of 564,706,973 is 1

Step 1: Since 706 > 564, we apply the division lemma to 706 and 564, to get

706 = 564 x 1 + 142

Step 2: Since the reminder 564 ≠ 0, we apply division lemma to 142 and 564, to get

564 = 142 x 3 + 138

Step 3: We consider the new divisor 142 and the new remainder 138, and apply the division lemma to get

142 = 138 x 1 + 4

We consider the new divisor 138 and the new remainder 4,and apply the division lemma to get

138 = 4 x 34 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 564 and 706 is 2

Notice that 2 = HCF(4,2) = HCF(138,4) = HCF(142,138) = HCF(564,142) = HCF(706,564) .

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

Step 1: Since 973 > 2, we apply the division lemma to 973 and 2, to get

973 = 2 x 486 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 973 is 1

Notice that 1 = HCF(2,1) = HCF(973,2) .
