HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 553, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 980, 553, 349 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 980, 553, 349 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 980, 553, 349 is 1.

HCF(980, 553, 349) = 1

Highest common factor (HCF) of 980, 553, 349 is 1.

Highest Common Factor of 980,553,349 using Euclid's algorithm

Highest Common Factor of 980,553,349 is 1

Step 1: Since 980 > 553, we apply the division lemma to 980 and 553, to get

980 = 553 x 1 + 427

Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 427 and 553, to get

553 = 427 x 1 + 126

Step 3: We consider the new divisor 427 and the new remainder 126, and apply the division lemma to get

427 = 126 x 3 + 49

We consider the new divisor 126 and the new remainder 49,and apply the division lemma to get

126 = 49 x 2 + 28

We consider the new divisor 49 and the new remainder 28,and apply the division lemma to get

49 = 28 x 1 + 21

We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get

28 = 21 x 1 + 7

We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get

21 = 7 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 980 and 553 is 7

Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(49,28) = HCF(126,49) = HCF(427,126) = HCF(553,427) = HCF(980,553) .


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

Step 1: Since 349 > 7, we apply the division lemma to 349 and 7, to get

349 = 7 x 49 + 6

Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get

7 = 6 x 1 + 1

Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 349 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(349,7) .
