HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 646, 160 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 550, 646, 160 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 550, 646, 160 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, 646, 160 is 2.

HCF(550, 646, 160) = 2

HCF of 550, 646, 160 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, 646, 160 is 2.

Highest Common Factor of 550,646,160 using Euclid's algorithm

Highest Common Factor of 550,646,160 is 2

Step 1: Since 646 > 550, we apply the division lemma to 646 and 550, to get

646 = 550 x 1 + 96

Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 96 and 550, to get

550 = 96 x 5 + 70

Step 3: We consider the new divisor 96 and the new remainder 70, and apply the division lemma to get

96 = 70 x 1 + 26

We consider the new divisor 70 and the new remainder 26,and apply the division lemma to get

70 = 26 x 2 + 18

We consider the new divisor 26 and the new remainder 18,and apply the division lemma to get

26 = 18 x 1 + 8

We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get

18 = 8 x 2 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 550 and 646 is 2

Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(26,18) = HCF(70,26) = HCF(96,70) = HCF(550,96) = HCF(646,550) .


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

Step 1: Since 160 > 2, we apply the division lemma to 160 and 2, to get

160 = 2 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 160 is 2

Notice that 2 = HCF(160,2) .
