HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 619, 11, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 358, 619, 11, 851 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 358, 619, 11, 851 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 358, 619, 11, 851 is 1.
HCF(358, 619, 11, 851) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 358, 619, 11, 851 is 1.
Step 1: Since 619 > 358, we apply the division lemma to 619 and 358, to get
619 = 358 x 1 + 261
Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 261 and 358, to get
358 = 261 x 1 + 97
Step 3: We consider the new divisor 261 and the new remainder 97, and apply the division lemma to get
261 = 97 x 2 + 67
We consider the new divisor 97 and the new remainder 67,and apply the division lemma to get
97 = 67 x 1 + 30
We consider the new divisor 67 and the new remainder 30,and apply the division lemma to get
67 = 30 x 2 + 7
We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get
30 = 7 x 4 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 358 and 619 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(67,30) = HCF(97,67) = HCF(261,97) = HCF(358,261) = HCF(619,358) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 11 > 1, we apply the division lemma to 11 and 1, to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 11 is 1
Notice that 1 = HCF(11,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 1, we apply the division lemma to 851 and 1, to get
851 = 1 x 851 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 851 is 1
Notice that 1 = HCF(851,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
