HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 561, 917, 182 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 685, 561, 917, 182 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 685, 561, 917, 182 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 685, 561, 917, 182 is 1.

HCF(685, 561, 917, 182) = 1

Highest Common Factor of 685,561,917,182 using Euclid's algorithm

Highest Common Factor of 685,561,917,182 is 1

Step 1: Since 685 > 561, we apply the division lemma to 685 and 561, to get

685 = 561 x 1 + 124

Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 124 and 561, to get

561 = 124 x 4 + 65

Step 3: We consider the new divisor 124 and the new remainder 65, and apply the division lemma to get

124 = 65 x 1 + 59

We consider the new divisor 65 and the new remainder 59,and apply the division lemma to get

65 = 59 x 1 + 6

We consider the new divisor 59 and the new remainder 6,and apply the division lemma to get

59 = 6 x 9 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 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 685 and 561 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(59,6) = HCF(65,59) = HCF(124,65) = HCF(561,124) = HCF(685,561) .

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

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

917 = 1 x 917 + 0

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

Notice that 1 = HCF(917,1) .

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

Step 1: Since 182 > 1, we apply the division lemma to 182 and 1, to get

182 = 1 x 182 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 182 is 1

Notice that 1 = HCF(182,1) .
