HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 438, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 802, 438, 917 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 802, 438, 917 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 802, 438, 917 is 1.

HCF(802, 438, 917) = 1

Highest common factor (HCF) of 802, 438, 917 is 1.

Highest Common Factor of 802,438,917 using Euclid's algorithm

Highest Common Factor of 802,438,917 is 1

Step 1: Since 802 > 438, we apply the division lemma to 802 and 438, to get

802 = 438 x 1 + 364

Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 364 and 438, to get

438 = 364 x 1 + 74

Step 3: We consider the new divisor 364 and the new remainder 74, and apply the division lemma to get

364 = 74 x 4 + 68

We consider the new divisor 74 and the new remainder 68,and apply the division lemma to get

74 = 68 x 1 + 6

We consider the new divisor 68 and the new remainder 6,and apply the division lemma to get

68 = 6 x 11 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 802 and 438 is 2

Notice that 2 = HCF(6,2) = HCF(68,6) = HCF(74,68) = HCF(364,74) = HCF(438,364) = HCF(802,438) .

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

Step 1: Since 917 > 2, we apply the division lemma to 917 and 2, to get

917 = 2 x 458 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 917 is 1

Notice that 1 = HCF(2,1) = HCF(917,2) .
