HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 423, 578 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 550, 423, 578 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 550, 423, 578 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 550, 423, 578 is 1.

HCF(550, 423, 578) = 1

HCF of 550, 423, 578 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 550, 423, 578 is 1.

Highest Common Factor of 550,423,578 using Euclid's algorithm

Highest Common Factor of 550,423,578 is 1

Step 1: Since 550 > 423, we apply the division lemma to 550 and 423, to get

550 = 423 x 1 + 127

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 127 and 423, to get

423 = 127 x 3 + 42

Step 3: We consider the new divisor 127 and the new remainder 42, and apply the division lemma to get

127 = 42 x 3 + 1

We consider the new divisor 42 and the new remainder 1, and apply the division lemma to get

42 = 1 x 42 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 550 and 423 is 1

Notice that 1 = HCF(42,1) = HCF(127,42) = HCF(423,127) = HCF(550,423) .


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

Step 1: Since 578 > 1, we apply the division lemma to 578 and 1, to get

578 = 1 x 578 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 578 is 1

Notice that 1 = HCF(578,1) .
