HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 959, 605 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 424, 959, 605 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 424, 959, 605 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 424, 959, 605 is 1.

HCF(424, 959, 605) = 1

Highest common factor (HCF) of 424, 959, 605 is 1.

Highest Common Factor of 424,959,605 using Euclid's algorithm

Highest Common Factor of 424,959,605 is 1

Step 1: Since 959 > 424, we apply the division lemma to 959 and 424, to get

959 = 424 x 2 + 111

Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 111 and 424, to get

424 = 111 x 3 + 91

Step 3: We consider the new divisor 111 and the new remainder 91, and apply the division lemma to get

111 = 91 x 1 + 20

We consider the new divisor 91 and the new remainder 20,and apply the division lemma to get

91 = 20 x 4 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 424 and 959 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(91,20) = HCF(111,91) = HCF(424,111) = HCF(959,424) .


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

Step 1: Since 605 > 1, we apply the division lemma to 605 and 1, to get

605 = 1 x 605 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 605 is 1

Notice that 1 = HCF(605,1) .
