HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 230, 909, 681, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 230, 909, 681, 619 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 230, 909, 681, 619 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 230, 909, 681, 619 is 1.
HCF(230, 909, 681, 619) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 230, 909, 681, 619 is 1.
Step 1: Since 909 > 230, we apply the division lemma to 909 and 230, to get
909 = 230 x 3 + 219
Step 2: Since the reminder 230 ≠ 0, we apply division lemma to 219 and 230, to get
230 = 219 x 1 + 11
Step 3: We consider the new divisor 219 and the new remainder 11, and apply the division lemma to get
219 = 11 x 19 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 230 and 909 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(219,11) = HCF(230,219) = HCF(909,230) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get
681 = 1 x 681 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1
Notice that 1 = HCF(681,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 619 > 1, we apply the division lemma to 619 and 1, to get
619 = 1 x 619 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 619 is 1
Notice that 1 = HCF(619,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
