HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 89, 59, 45 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 89, 59, 45 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 89, 59, 45 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 89, 59, 45 is 1.

HCF(89, 59, 45) = 1

HCF of 89, 59, 45 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 89, 59, 45 is 1.

Highest Common Factor of 89,59,45 using Euclid's algorithm

Highest Common Factor of 89,59,45 is 1

Step 1: Since 89 > 59, we apply the division lemma to 89 and 59, to get

89 = 59 x 1 + 30

Step 2: Since the reminder 59 ≠ 0, we apply division lemma to 30 and 59, to get

59 = 30 x 1 + 29

Step 3: We consider the new divisor 30 and the new remainder 29, and apply the division lemma to get

30 = 29 x 1 + 1

We consider the new divisor 29 and the new remainder 1, and apply the division lemma to get

29 = 1 x 29 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 89 and 59 is 1

Notice that 1 = HCF(29,1) = HCF(30,29) = HCF(59,30) = HCF(89,59) .


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

Step 1: Since 45 > 1, we apply the division lemma to 45 and 1, to get

45 = 1 x 45 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 45 is 1

Notice that 1 = HCF(45,1) .
