HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 49, 98, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 49, 98, 909 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 49, 98, 909 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 49, 98, 909 is 1.
HCF(49, 98, 909) = 1
HCF of 49, 98, 909 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 49, 98, 909 is 1.
Highest Common Factor of 49,98,909 is 1
Step 1: Since 98 > 49, we apply the division lemma to 98 and 49, to get
98 = 49 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 49, the HCF of 49 and 98 is 49
Notice that 49 = HCF(98,49) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 49, we apply the division lemma to 909 and 49, to get
909 = 49 x 18 + 27
Step 2: Since the reminder 49 ≠ 0, we apply division lemma to 27 and 49, to get
49 = 27 x 1 + 22
Step 3: We consider the new divisor 27 and the new remainder 22, and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 49 and 909 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(909,49) .
