HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 45, 15, 92 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 45, 15, 92 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 45, 15, 92 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 45, 15, 92 is 1.

HCF(45, 15, 92) = 1

HCF of 45, 15, 92 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 45, 15, 92 is 1.

Highest Common Factor of 45,15,92 using Euclid's algorithm

Highest Common Factor of 45,15,92 is 1

Step 1: Since 45 > 15, we apply the division lemma to 45 and 15, to get

45 = 15 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 45 and 15 is 15

Notice that 15 = HCF(45,15) .

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

Step 1: Since 92 > 15, we apply the division lemma to 92 and 15, to get

92 = 15 x 6 + 2

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 2 and 15, to get

15 = 2 x 7 + 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 15 and 92 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(92,15) .
