HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 100, 140, 50 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 361, 100, 140, 50 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 361, 100, 140, 50 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 361, 100, 140, 50 is 1.
HCF(361, 100, 140, 50) = 1
HCF of 361, 100, 140, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 361, 100, 140, 50 is 1.
Highest Common Factor of 361,100,140,50 is 1
Step 1: Since 361 > 100, we apply the division lemma to 361 and 100, to get
361 = 100 x 3 + 61
Step 2: Since the reminder 100 ≠ 0, we apply division lemma to 61 and 100, to get
100 = 61 x 1 + 39
Step 3: We consider the new divisor 61 and the new remainder 39, and apply the division lemma to get
61 = 39 x 1 + 22
We consider the new divisor 39 and the new remainder 22,and apply the division lemma to get
39 = 22 x 1 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 361 and 100 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(39,22) = HCF(61,39) = HCF(100,61) = HCF(361,100) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 1, we apply the division lemma to 140 and 1, to get
140 = 1 x 140 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 140 is 1
Notice that 1 = HCF(140,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 1, we apply the division lemma to 50 and 1, to get
50 = 1 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 50 is 1
Notice that 1 = HCF(50,1) .
