HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 374, 604, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 374, 604, 861 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 374, 604, 861 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 374, 604, 861 is 1.

HCF(374, 604, 861) = 1

HCF of 374, 604, 861 using Euclid's algorithm

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

Highest common factor (HCF) of 374, 604, 861 is 1.

Highest Common Factor of 374,604,861 using Euclid's algorithm

Highest Common Factor of 374,604,861 is 1

Step 1: Since 604 > 374, we apply the division lemma to 604 and 374, to get

604 = 374 x 1 + 230

Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 230 and 374, to get

374 = 230 x 1 + 144

Step 3: We consider the new divisor 230 and the new remainder 144, and apply the division lemma to get

230 = 144 x 1 + 86

We consider the new divisor 144 and the new remainder 86,and apply the division lemma to get

144 = 86 x 1 + 58

We consider the new divisor 86 and the new remainder 58,and apply the division lemma to get

86 = 58 x 1 + 28

We consider the new divisor 58 and the new remainder 28,and apply the division lemma to get

58 = 28 x 2 + 2

We consider the new divisor 28 and the new remainder 2,and apply the division lemma to get

28 = 2 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 374 and 604 is 2

Notice that 2 = HCF(28,2) = HCF(58,28) = HCF(86,58) = HCF(144,86) = HCF(230,144) = HCF(374,230) = HCF(604,374) .

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

Step 1: Since 861 > 2, we apply the division lemma to 861 and 2, to get

861 = 2 x 430 + 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 861 is 1

Notice that 1 = HCF(2,1) = HCF(861,2) .
