HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 545, 417 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 545, 417 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 545, 417 is 1.

HCF(545, 417) = 1

HCF of 545, 417 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 545, 417 is 1.

Highest Common Factor of 545,417 using Euclid's algorithm

Highest Common Factor of 545,417 is 1

Step 1: Since 545 > 417, we apply the division lemma to 545 and 417, to get

545 = 417 x 1 + 128

Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 128 and 417, to get

417 = 128 x 3 + 33

Step 3: We consider the new divisor 128 and the new remainder 33, and apply the division lemma to get

128 = 33 x 3 + 29

We consider the new divisor 33 and the new remainder 29,and apply the division lemma to get

33 = 29 x 1 + 4

We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get

29 = 4 x 7 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 545 and 417 is 1

Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(128,33) = HCF(417,128) = HCF(545,417) .
