HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 535, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 535, 13 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 975, 535, 13 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 975, 535, 13 is 1.
HCF(975, 535, 13) = 1
HCF of 975, 535, 13 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 535, 13 is 1.
Highest Common Factor of 975,535,13 is 1
Step 1: Since 975 > 535, we apply the division lemma to 975 and 535, to get
975 = 535 x 1 + 440
Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 440 and 535, to get
535 = 440 x 1 + 95
Step 3: We consider the new divisor 440 and the new remainder 95, and apply the division lemma to get
440 = 95 x 4 + 60
We consider the new divisor 95 and the new remainder 60,and apply the division lemma to get
95 = 60 x 1 + 35
We consider the new divisor 60 and the new remainder 35,and apply the division lemma to get
60 = 35 x 1 + 25
We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get
35 = 25 x 1 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 975 and 535 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(60,35) = HCF(95,60) = HCF(440,95) = HCF(535,440) = HCF(975,535) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 5, we apply the division lemma to 13 and 5, to get
13 = 5 x 2 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 13 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) .
