HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 536, 989, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 536, 989, 545 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 536, 989, 545 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 536, 989, 545 is 1.

HCF(536, 989, 545) = 1

HCF of 536, 989, 545 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 536, 989, 545 is 1.

Highest Common Factor of 536,989,545 using Euclid's algorithm

Highest Common Factor of 536,989,545 is 1

Step 1: Since 989 > 536, we apply the division lemma to 989 and 536, to get

989 = 536 x 1 + 453

Step 2: Since the reminder 536 ≠ 0, we apply division lemma to 453 and 536, to get

536 = 453 x 1 + 83

Step 3: We consider the new divisor 453 and the new remainder 83, and apply the division lemma to get

453 = 83 x 5 + 38

We consider the new divisor 83 and the new remainder 38,and apply the division lemma to get

83 = 38 x 2 + 7

We consider the new divisor 38 and the new remainder 7,and apply the division lemma to get

38 = 7 x 5 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 536 and 989 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(38,7) = HCF(83,38) = HCF(453,83) = HCF(536,453) = HCF(989,536) .

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

Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get

545 = 1 x 545 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1

Notice that 1 = HCF(545,1) .
