HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 192, 220, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 192, 220, 553 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 192, 220, 553 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 192, 220, 553 is 1.

HCF(192, 220, 553) = 1

HCF of 192, 220, 553 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 192, 220, 553 is 1.

Highest Common Factor of 192,220,553 using Euclid's algorithm

Highest Common Factor of 192,220,553 is 1

Step 1: Since 220 > 192, we apply the division lemma to 220 and 192, to get

220 = 192 x 1 + 28

Step 2: Since the reminder 192 ≠ 0, we apply division lemma to 28 and 192, to get

192 = 28 x 6 + 24

Step 3: We consider the new divisor 28 and the new remainder 24, and apply the division lemma to get

28 = 24 x 1 + 4

We consider the new divisor 24 and the new remainder 4, and apply the division lemma to get

24 = 4 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 192 and 220 is 4

Notice that 4 = HCF(24,4) = HCF(28,24) = HCF(192,28) = HCF(220,192) .

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

Step 1: Since 553 > 4, we apply the division lemma to 553 and 4, to get

553 = 4 x 138 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 553 is 1

Notice that 1 = HCF(4,1) = HCF(553,4) .
