HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 379, 620, 840 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 379, 620, 840 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 379, 620, 840 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 379, 620, 840 is 1.

HCF(379, 620, 840) = 1

HCF of 379, 620, 840 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 379, 620, 840 is 1.

Highest Common Factor of 379,620,840 using Euclid's algorithm

Highest Common Factor of 379,620,840 is 1

Step 1: Since 620 > 379, we apply the division lemma to 620 and 379, to get

620 = 379 x 1 + 241

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 241 and 379, to get

379 = 241 x 1 + 138

Step 3: We consider the new divisor 241 and the new remainder 138, and apply the division lemma to get

241 = 138 x 1 + 103

We consider the new divisor 138 and the new remainder 103,and apply the division lemma to get

138 = 103 x 1 + 35

We consider the new divisor 103 and the new remainder 35,and apply the division lemma to get

103 = 35 x 2 + 33

We consider the new divisor 35 and the new remainder 33,and apply the division lemma to get

35 = 33 x 1 + 2

We consider the new divisor 33 and the new remainder 2,and apply the division lemma to get

33 = 2 x 16 + 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 379 and 620 is 1

Notice that 1 = HCF(2,1) = HCF(33,2) = HCF(35,33) = HCF(103,35) = HCF(138,103) = HCF(241,138) = HCF(379,241) = HCF(620,379) .

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

Step 1: Since 840 > 1, we apply the division lemma to 840 and 1, to get

840 = 1 x 840 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 840 is 1

Notice that 1 = HCF(840,1) .
