HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 208 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 550, 208 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, 208 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, 208 is 2.
HCF(550, 208) = 2
HCF of 550, 208 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 550, 208 is 2.
Highest Common Factor of 550,208 is 2
Step 1: Since 550 > 208, we apply the division lemma to 550 and 208, to get
550 = 208 x 2 + 134
Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 134 and 208, to get
208 = 134 x 1 + 74
Step 3: We consider the new divisor 134 and the new remainder 74, and apply the division lemma to get
134 = 74 x 1 + 60
We consider the new divisor 74 and the new remainder 60,and apply the division lemma to get
74 = 60 x 1 + 14
We consider the new divisor 60 and the new remainder 14,and apply the division lemma to get
60 = 14 x 4 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 550 and 208 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(60,14) = HCF(74,60) = HCF(134,74) = HCF(208,134) = HCF(550,208) .
