HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 940, 988, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 940, 988, 159 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 940, 988, 159 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 940, 988, 159 is 1.
HCF(940, 988, 159) = 1
HCF of 940, 988, 159 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 940, 988, 159 is 1.
Highest Common Factor of 940,988,159 is 1
Step 1: Since 988 > 940, we apply the division lemma to 988 and 940, to get
988 = 940 x 1 + 48
Step 2: Since the reminder 940 ≠ 0, we apply division lemma to 48 and 940, to get
940 = 48 x 19 + 28
Step 3: We consider the new divisor 48 and the new remainder 28, and apply the division lemma to get
48 = 28 x 1 + 20
We consider the new divisor 28 and the new remainder 20,and apply the division lemma to get
28 = 20 x 1 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 940 and 988 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(28,20) = HCF(48,28) = HCF(940,48) = HCF(988,940) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 159 > 4, we apply the division lemma to 159 and 4, to get
159 = 4 x 39 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 159 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(159,4) .
