HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 22, 77, 648, 800 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 22, 77, 648, 800 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 22, 77, 648, 800 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 22, 77, 648, 800 is 1.

HCF(22, 77, 648, 800) = 1

HCF of 22, 77, 648, 800 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 22, 77, 648, 800 is 1.

Highest Common Factor of 22,77,648,800 using Euclid's algorithm

Highest Common Factor of 22,77,648,800 is 1

Step 1: Since 77 > 22, we apply the division lemma to 77 and 22, to get

77 = 22 x 3 + 11

Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 11 and 22, to get

22 = 11 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 22 and 77 is 11

Notice that 11 = HCF(22,11) = HCF(77,22) .


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

Step 1: Since 648 > 11, we apply the division lemma to 648 and 11, to get

648 = 11 x 58 + 10

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get

11 = 10 x 1 + 1

Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 648 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(648,11) .


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

Step 1: Since 800 > 1, we apply the division lemma to 800 and 1, to get

800 = 1 x 800 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 800 is 1

Notice that 1 = HCF(800,1) .
