HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 555, 554, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 673, 555, 554, 399 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 673, 555, 554, 399 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 673, 555, 554, 399 is 1.

HCF(673, 555, 554, 399) = 1

Highest common factor (HCF) of 673, 555, 554, 399 is 1.

Highest Common Factor of 673,555,554,399 using Euclid's algorithm

Highest Common Factor of 673,555,554,399 is 1

Step 1: Since 673 > 555, we apply the division lemma to 673 and 555, to get

673 = 555 x 1 + 118

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 118 and 555, to get

555 = 118 x 4 + 83

Step 3: We consider the new divisor 118 and the new remainder 83, and apply the division lemma to get

118 = 83 x 1 + 35

We consider the new divisor 83 and the new remainder 35,and apply the division lemma to get

83 = 35 x 2 + 13

We consider the new divisor 35 and the new remainder 13,and apply the division lemma to get

35 = 13 x 2 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 673 and 555 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(35,13) = HCF(83,35) = HCF(118,83) = HCF(555,118) = HCF(673,555) .

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

Step 1: Since 554 > 1, we apply the division lemma to 554 and 1, to get

554 = 1 x 554 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 554 is 1

Notice that 1 = HCF(554,1) .

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

Step 1: Since 399 > 1, we apply the division lemma to 399 and 1, to get

399 = 1 x 399 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 399 is 1

Notice that 1 = HCF(399,1) .
