HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 353, 402 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 917, 353, 402 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 917, 353, 402 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 917, 353, 402 is 1.

HCF(917, 353, 402) = 1

Highest common factor (HCF) of 917, 353, 402 is 1.

Highest Common Factor of 917,353,402 using Euclid's algorithm

Highest Common Factor of 917,353,402 is 1

Step 1: Since 917 > 353, we apply the division lemma to 917 and 353, to get

917 = 353 x 2 + 211

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 211 and 353, to get

353 = 211 x 1 + 142

Step 3: We consider the new divisor 211 and the new remainder 142, and apply the division lemma to get

211 = 142 x 1 + 69

We consider the new divisor 142 and the new remainder 69,and apply the division lemma to get

142 = 69 x 2 + 4

We consider the new divisor 69 and the new remainder 4,and apply the division lemma to get

69 = 4 x 17 + 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 917 and 353 is 1

Notice that 1 = HCF(4,1) = HCF(69,4) = HCF(142,69) = HCF(211,142) = HCF(353,211) = HCF(917,353) .

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

Step 1: Since 402 > 1, we apply the division lemma to 402 and 1, to get

402 = 1 x 402 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 402 is 1

Notice that 1 = HCF(402,1) .
