HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 189, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 218, 189, 553 is 1 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 218, 189, 553 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 218, 189, 553 is 1.
HCF(218, 189, 553) = 1
HCF of 218, 189, 553 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 218, 189, 553 is 1.
Highest Common Factor of 218,189,553 is 1
Step 1: Since 218 > 189, we apply the division lemma to 218 and 189, to get
218 = 189 x 1 + 29
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 29 and 189, to get
189 = 29 x 6 + 15
Step 3: We consider the new divisor 29 and the new remainder 15, and apply the division lemma to get
29 = 15 x 1 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 218 and 189 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(189,29) = HCF(218,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 553 > 1, we apply the division lemma to 553 and 1, to get
553 = 1 x 553 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 553 is 1
Notice that 1 = HCF(553,1) .
