HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 499, 909, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 499, 909, 421 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 499, 909, 421 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 499, 909, 421 is 1.
HCF(499, 909, 421) = 1
HCF of 499, 909, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 499, 909, 421 is 1.
Highest Common Factor of 499,909,421 is 1
Step 1: Since 909 > 499, we apply the division lemma to 909 and 499, to get
909 = 499 x 1 + 410
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 410 and 499, to get
499 = 410 x 1 + 89
Step 3: We consider the new divisor 410 and the new remainder 89, and apply the division lemma to get
410 = 89 x 4 + 54
We consider the new divisor 89 and the new remainder 54,and apply the division lemma to get
89 = 54 x 1 + 35
We consider the new divisor 54 and the new remainder 35,and apply the division lemma to get
54 = 35 x 1 + 19
We consider the new divisor 35 and the new remainder 19,and apply the division lemma to get
35 = 19 x 1 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 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 499 and 909 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(35,19) = HCF(54,35) = HCF(89,54) = HCF(410,89) = HCF(499,410) = HCF(909,499) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
