HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 404, 294, 42 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 404, 294, 42 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, 404, 294, 42 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, 404, 294, 42 is 1.
HCF(909, 404, 294, 42) = 1
HCF of 909, 404, 294, 42 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 404, 294, 42 is 1.
Highest Common Factor of 909,404,294,42 is 1
Step 1: Since 909 > 404, we apply the division lemma to 909 and 404, to get
909 = 404 x 2 + 101
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 101 and 404, to get
404 = 101 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 101, the HCF of 909 and 404 is 101
Notice that 101 = HCF(404,101) = HCF(909,404) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 294 > 101, we apply the division lemma to 294 and 101, to get
294 = 101 x 2 + 92
Step 2: Since the reminder 101 ≠ 0, we apply division lemma to 92 and 101, to get
101 = 92 x 1 + 9
Step 3: We consider the new divisor 92 and the new remainder 9, and apply the division lemma to get
92 = 9 x 10 + 2
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 101 and 294 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(92,9) = HCF(101,92) = HCF(294,101) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
