HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 149, 66, 469 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 545, 149, 66, 469 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, 149, 66, 469 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, 149, 66, 469 is 1.

HCF(545, 149, 66, 469) = 1

HCF of 545, 149, 66, 469 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, 149, 66, 469 is 1.

Highest Common Factor of 545,149,66,469 using Euclid's algorithm

Highest Common Factor of 545,149,66,469 is 1

Step 1: Since 545 > 149, we apply the division lemma to 545 and 149, to get

545 = 149 x 3 + 98

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 98 and 149, to get

149 = 98 x 1 + 51

Step 3: We consider the new divisor 98 and the new remainder 51, and apply the division lemma to get

98 = 51 x 1 + 47

We consider the new divisor 51 and the new remainder 47,and apply the division lemma to get

51 = 47 x 1 + 4

We consider the new divisor 47 and the new remainder 4,and apply the division lemma to get

47 = 4 x 11 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 545 and 149 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(47,4) = HCF(51,47) = HCF(98,51) = HCF(149,98) = HCF(545,149) .


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

Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get

66 = 1 x 66 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1

Notice that 1 = HCF(66,1) .


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

Step 1: Since 469 > 1, we apply the division lemma to 469 and 1, to get

469 = 1 x 469 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 469 is 1

Notice that 1 = HCF(469,1) .
