HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 672, 353, 99 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 672, 353, 99 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 189, 672, 353, 99 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 189, 672, 353, 99 is 1.
HCF(189, 672, 353, 99) = 1
HCF of 189, 672, 353, 99 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 672, 353, 99 is 1.
Highest Common Factor of 189,672,353,99 is 1
Step 1: Since 672 > 189, we apply the division lemma to 672 and 189, to get
672 = 189 x 3 + 105
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 105 and 189, to get
189 = 105 x 1 + 84
Step 3: We consider the new divisor 105 and the new remainder 84, and apply the division lemma to get
105 = 84 x 1 + 21
We consider the new divisor 84 and the new remainder 21, and apply the division lemma to get
84 = 21 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 189 and 672 is 21
Notice that 21 = HCF(84,21) = HCF(105,84) = HCF(189,105) = HCF(672,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 21, we apply the division lemma to 353 and 21, to get
353 = 21 x 16 + 17
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 17 and 21, to get
21 = 17 x 1 + 4
Step 3: We consider the new divisor 17 and the new remainder 4, and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 21 and 353 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(353,21) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 1, we apply the division lemma to 99 and 1, to get
99 = 1 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 99 is 1
Notice that 1 = HCF(99,1) .
