HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 563, 320, 640 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 563, 320, 640 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 563, 320, 640 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 563, 320, 640 is 1.

HCF(563, 320, 640) = 1

HCF of 563, 320, 640 using Euclid's algorithm

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

Highest common factor (HCF) of 563, 320, 640 is 1.

Highest Common Factor of 563,320,640 using Euclid's algorithm

Highest Common Factor of 563,320,640 is 1

Step 1: Since 563 > 320, we apply the division lemma to 563 and 320, to get

563 = 320 x 1 + 243

Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 243 and 320, to get

320 = 243 x 1 + 77

Step 3: We consider the new divisor 243 and the new remainder 77, and apply the division lemma to get

243 = 77 x 3 + 12

We consider the new divisor 77 and the new remainder 12,and apply the division lemma to get

77 = 12 x 6 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 563 and 320 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(243,77) = HCF(320,243) = HCF(563,320) .

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

Step 1: Since 640 > 1, we apply the division lemma to 640 and 1, to get

640 = 1 x 640 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 640 is 1

Notice that 1 = HCF(640,1) .
