HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 197, 536, 742, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 197, 536, 742, 61 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 197, 536, 742, 61 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 197, 536, 742, 61 is 1.
HCF(197, 536, 742, 61) = 1
HCF of 197, 536, 742, 61 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 197, 536, 742, 61 is 1.
Highest Common Factor of 197,536,742,61 is 1
Step 1: Since 536 > 197, we apply the division lemma to 536 and 197, to get
536 = 197 x 2 + 142
Step 2: Since the reminder 197 ≠ 0, we apply division lemma to 142 and 197, to get
197 = 142 x 1 + 55
Step 3: We consider the new divisor 142 and the new remainder 55, and apply the division lemma to get
142 = 55 x 2 + 32
We consider the new divisor 55 and the new remainder 32,and apply the division lemma to get
55 = 32 x 1 + 23
We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get
32 = 23 x 1 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 197 and 536 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(55,32) = HCF(142,55) = HCF(197,142) = HCF(536,197) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 742 > 1, we apply the division lemma to 742 and 1, to get
742 = 1 x 742 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 742 is 1
Notice that 1 = HCF(742,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
