HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 360, 995, 445, 137 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 360, 995, 445, 137 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 360, 995, 445, 137 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 360, 995, 445, 137 is 1.
HCF(360, 995, 445, 137) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 360, 995, 445, 137 is 1.
Step 1: Since 995 > 360, we apply the division lemma to 995 and 360, to get
995 = 360 x 2 + 275
Step 2: Since the reminder 360 ≠ 0, we apply division lemma to 275 and 360, to get
360 = 275 x 1 + 85
Step 3: We consider the new divisor 275 and the new remainder 85, and apply the division lemma to get
275 = 85 x 3 + 20
We consider the new divisor 85 and the new remainder 20,and apply the division lemma to get
85 = 20 x 4 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 360 and 995 is 5
Notice that 5 = HCF(20,5) = HCF(85,20) = HCF(275,85) = HCF(360,275) = HCF(995,360) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 5, we apply the division lemma to 445 and 5, to get
445 = 5 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 445 is 5
Notice that 5 = HCF(445,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 137 > 5, we apply the division lemma to 137 and 5, to get
137 = 5 x 27 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 137 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(137,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
