HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 562, 701 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 562, 701 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 909, 562, 701 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 909, 562, 701 is 1.
HCF(909, 562, 701) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 562, 701 is 1.
Step 1: Since 909 > 562, we apply the division lemma to 909 and 562, to get
909 = 562 x 1 + 347
Step 2: Since the reminder 562 ≠ 0, we apply division lemma to 347 and 562, to get
562 = 347 x 1 + 215
Step 3: We consider the new divisor 347 and the new remainder 215, and apply the division lemma to get
347 = 215 x 1 + 132
We consider the new divisor 215 and the new remainder 132,and apply the division lemma to get
215 = 132 x 1 + 83
We consider the new divisor 132 and the new remainder 83,and apply the division lemma to get
132 = 83 x 1 + 49
We consider the new divisor 83 and the new remainder 49,and apply the division lemma to get
83 = 49 x 1 + 34
We consider the new divisor 49 and the new remainder 34,and apply the division lemma to get
49 = 34 x 1 + 15
We consider the new divisor 34 and the new remainder 15,and apply the division lemma to get
34 = 15 x 2 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 909 and 562 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(34,15) = HCF(49,34) = HCF(83,49) = HCF(132,83) = HCF(215,132) = HCF(347,215) = HCF(562,347) = HCF(909,562) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 701 > 1, we apply the division lemma to 701 and 1, to get
701 = 1 x 701 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 701 is 1
Notice that 1 = HCF(701,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
