HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 350, 935 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 350, 935 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 553, 350, 935 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, 350, 935 is 1.
HCF(553, 350, 935) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 350, 935 is 1.
Step 1: Since 553 > 350, we apply the division lemma to 553 and 350, to get
553 = 350 x 1 + 203
Step 2: Since the reminder 350 ≠ 0, we apply division lemma to 203 and 350, to get
350 = 203 x 1 + 147
Step 3: We consider the new divisor 203 and the new remainder 147, and apply the division lemma to get
203 = 147 x 1 + 56
We consider the new divisor 147 and the new remainder 56,and apply the division lemma to get
147 = 56 x 2 + 35
We consider the new divisor 56 and the new remainder 35,and apply the division lemma to get
56 = 35 x 1 + 21
We consider the new divisor 35 and the new remainder 21,and apply the division lemma to get
35 = 21 x 1 + 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 350 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(56,35) = HCF(147,56) = HCF(203,147) = HCF(350,203) = HCF(553,350) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 935 > 7, we apply the division lemma to 935 and 7, to get
935 = 7 x 133 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 935 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(935,7) .
Here are some samples of HCF using Euclid's Algorithm calculations.
