HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 59, 42, 307, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 59, 42, 307, 818 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 59, 42, 307, 818 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 59, 42, 307, 818 is 1.

HCF(59, 42, 307, 818) = 1

HCF of 59, 42, 307, 818 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 59, 42, 307, 818 is 1.

Highest Common Factor of 59,42,307,818 using Euclid's algorithm

Highest Common Factor of 59,42,307,818 is 1

Step 1: Since 59 > 42, we apply the division lemma to 59 and 42, to get

59 = 42 x 1 + 17

Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 17 and 42, to get

42 = 17 x 2 + 8

Step 3: We consider the new divisor 17 and the new remainder 8, and apply the division lemma to get

17 = 8 x 2 + 1

We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 59 and 42 is 1

Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(42,17) = HCF(59,42) .


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

Step 1: Since 307 > 1, we apply the division lemma to 307 and 1, to get

307 = 1 x 307 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 307 is 1

Notice that 1 = HCF(307,1) .


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

Step 1: Since 818 > 1, we apply the division lemma to 818 and 1, to get

818 = 1 x 818 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 818 is 1

Notice that 1 = HCF(818,1) .
