HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 840 i.e. 10 the largest integer that leaves a remainder zero for all numbers.

HCF of 550, 840 is 10 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, 840 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, 840 is 10.

HCF(550, 840) = 10

HCF of 550, 840 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, 840 is 10.

Highest Common Factor of 550,840 using Euclid's algorithm

Highest Common Factor of 550,840 is 10

Step 1: Since 840 > 550, we apply the division lemma to 840 and 550, to get

840 = 550 x 1 + 290

Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 290 and 550, to get

550 = 290 x 1 + 260

Step 3: We consider the new divisor 290 and the new remainder 260, and apply the division lemma to get

290 = 260 x 1 + 30

We consider the new divisor 260 and the new remainder 30,and apply the division lemma to get

260 = 30 x 8 + 20

We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get

30 = 20 x 1 + 10

We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get

20 = 10 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 550 and 840 is 10

Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(260,30) = HCF(290,260) = HCF(550,290) = HCF(840,550) .
