HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 550 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 802, 550 is 2 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 802, 550 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 802, 550 is 2.

HCF(802, 550) = 2

HCF of 802, 550 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 802, 550 is 2.

Highest Common Factor of 802,550 using Euclid's algorithm

Highest Common Factor of 802,550 is 2

Step 1: Since 802 > 550, we apply the division lemma to 802 and 550, to get

802 = 550 x 1 + 252

Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 252 and 550, to get

550 = 252 x 2 + 46

Step 3: We consider the new divisor 252 and the new remainder 46, and apply the division lemma to get

252 = 46 x 5 + 22

We consider the new divisor 46 and the new remainder 22,and apply the division lemma to get

46 = 22 x 2 + 2

We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get

22 = 2 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 802 and 550 is 2

Notice that 2 = HCF(22,2) = HCF(46,22) = HCF(252,46) = HCF(550,252) = HCF(802,550) .
