HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 562, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 340, 562, 961 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 340, 562, 961 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 340, 562, 961 is 1.

HCF(340, 562, 961) = 1

HCF of 340, 562, 961 using Euclid's algorithm

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

Highest common factor (HCF) of 340, 562, 961 is 1.

Highest Common Factor of 340,562,961 using Euclid's algorithm

Highest Common Factor of 340,562,961 is 1

Step 1: Since 562 > 340, we apply the division lemma to 562 and 340, to get

562 = 340 x 1 + 222

Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 222 and 340, to get

340 = 222 x 1 + 118

Step 3: We consider the new divisor 222 and the new remainder 118, and apply the division lemma to get

222 = 118 x 1 + 104

We consider the new divisor 118 and the new remainder 104,and apply the division lemma to get

118 = 104 x 1 + 14

We consider the new divisor 104 and the new remainder 14,and apply the division lemma to get

104 = 14 x 7 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 340 and 562 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(104,14) = HCF(118,104) = HCF(222,118) = HCF(340,222) = HCF(562,340) .

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

Step 1: Since 961 > 2, we apply the division lemma to 961 and 2, to get

961 = 2 x 480 + 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 961 is 1

Notice that 1 = HCF(2,1) = HCF(961,2) .
