HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 210 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 210 is 7 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 553, 210 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 553, 210 is 7.
HCF(553, 210) = 7
HCF of 553, 210 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 210 is 7.
Highest Common Factor of 553,210 is 7
Step 1: Since 553 > 210, we apply the division lemma to 553 and 210, to get
553 = 210 x 2 + 133
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 133 and 210, to get
210 = 133 x 1 + 77
Step 3: We consider the new divisor 133 and the new remainder 77, and apply the division lemma to get
133 = 77 x 1 + 56
We consider the new divisor 77 and the new remainder 56,and apply the division lemma to get
77 = 56 x 1 + 21
We consider the new divisor 56 and the new remainder 21,and apply the division lemma to get
56 = 21 x 2 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 553 and 210 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(56,21) = HCF(77,56) = HCF(133,77) = HCF(210,133) = HCF(553,210) .
