HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 506, 911, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 506, 911, 53 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 715, 506, 911, 53 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 715, 506, 911, 53 is 1.
HCF(715, 506, 911, 53) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 506, 911, 53 is 1.
Step 1: Since 715 > 506, we apply the division lemma to 715 and 506, to get
715 = 506 x 1 + 209
Step 2: Since the reminder 506 ≠ 0, we apply division lemma to 209 and 506, to get
506 = 209 x 2 + 88
Step 3: We consider the new divisor 209 and the new remainder 88, and apply the division lemma to get
209 = 88 x 2 + 33
We consider the new divisor 88 and the new remainder 33,and apply the division lemma to get
88 = 33 x 2 + 22
We consider the new divisor 33 and the new remainder 22,and apply the division lemma to get
33 = 22 x 1 + 11
We consider the new divisor 22 and the new remainder 11,and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 715 and 506 is 11
Notice that 11 = HCF(22,11) = HCF(33,22) = HCF(88,33) = HCF(209,88) = HCF(506,209) = HCF(715,506) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 911 > 11, we apply the division lemma to 911 and 11, to get
911 = 11 x 82 + 9
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 9 and 11, to get
11 = 9 x 1 + 2
Step 3: We consider the new divisor 9 and the new remainder 2, and apply the division lemma to get
9 = 2 x 4 + 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 11 and 911 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(911,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1
Notice that 1 = HCF(53,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
