HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 347, 979, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 347, 979, 557 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 347, 979, 557 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 347, 979, 557 is 1.

HCF(347, 979, 557) = 1

Highest common factor (HCF) of 347, 979, 557 is 1.

Highest Common Factor of 347,979,557 using Euclid's algorithm

Highest Common Factor of 347,979,557 is 1

Step 1: Since 979 > 347, we apply the division lemma to 979 and 347, to get

979 = 347 x 2 + 285

Step 2: Since the reminder 347 ≠ 0, we apply division lemma to 285 and 347, to get

347 = 285 x 1 + 62

Step 3: We consider the new divisor 285 and the new remainder 62, and apply the division lemma to get

285 = 62 x 4 + 37

We consider the new divisor 62 and the new remainder 37,and apply the division lemma to get

62 = 37 x 1 + 25

We consider the new divisor 37 and the new remainder 25,and apply the division lemma to get

37 = 25 x 1 + 12

We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get

25 = 12 x 2 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 347 and 979 is 1

Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(37,25) = HCF(62,37) = HCF(285,62) = HCF(347,285) = HCF(979,347) .

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

Step 1: Since 557 > 1, we apply the division lemma to 557 and 1, to get

557 = 1 x 557 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 557 is 1

Notice that 1 = HCF(557,1) .
