HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 818, 451, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 669, 818, 451, 439 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 669, 818, 451, 439 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 669, 818, 451, 439 is 1.

HCF(669, 818, 451, 439) = 1

HCF of 669, 818, 451, 439 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 669, 818, 451, 439 is 1.

Highest Common Factor of 669,818,451,439 using Euclid's algorithm

Highest Common Factor of 669,818,451,439 is 1

Step 1: Since 818 > 669, we apply the division lemma to 818 and 669, to get

818 = 669 x 1 + 149

Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 149 and 669, to get

669 = 149 x 4 + 73

Step 3: We consider the new divisor 149 and the new remainder 73, and apply the division lemma to get

149 = 73 x 2 + 3

We consider the new divisor 73 and the new remainder 3,and apply the division lemma to get

73 = 3 x 24 + 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 669 and 818 is 1

Notice that 1 = HCF(3,1) = HCF(73,3) = HCF(149,73) = HCF(669,149) = HCF(818,669) .


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

Step 1: Since 451 > 1, we apply the division lemma to 451 and 1, to get

451 = 1 x 451 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 451 is 1

Notice that 1 = HCF(451,1) .


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

Step 1: Since 439 > 1, we apply the division lemma to 439 and 1, to get

439 = 1 x 439 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 439 is 1

Notice that 1 = HCF(439,1) .
