HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 547, 689, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 547, 689, 355 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 547, 689, 355 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 547, 689, 355 is 1.

HCF(547, 689, 355) = 1

Highest common factor (HCF) of 547, 689, 355 is 1.

Highest Common Factor of 547,689,355 using Euclid's algorithm

Highest Common Factor of 547,689,355 is 1

Step 1: Since 689 > 547, we apply the division lemma to 689 and 547, to get

689 = 547 x 1 + 142

Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 142 and 547, to get

547 = 142 x 3 + 121

Step 3: We consider the new divisor 142 and the new remainder 121, and apply the division lemma to get

142 = 121 x 1 + 21

We consider the new divisor 121 and the new remainder 21,and apply the division lemma to get

121 = 21 x 5 + 16

We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get

21 = 16 x 1 + 5

We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get

16 = 5 x 3 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 547 and 689 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(121,21) = HCF(142,121) = HCF(547,142) = HCF(689,547) .

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

Step 1: Since 355 > 1, we apply the division lemma to 355 and 1, to get

355 = 1 x 355 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 355 is 1

Notice that 1 = HCF(355,1) .
