HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 478, 849 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 662, 478, 849 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 662, 478, 849 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 662, 478, 849 is 1.
HCF(662, 478, 849) = 1
HCF of 662, 478, 849 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 662, 478, 849 is 1.
Highest Common Factor of 662,478,849 is 1
Step 1: Since 662 > 478, we apply the division lemma to 662 and 478, to get
662 = 478 x 1 + 184
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 184 and 478, to get
478 = 184 x 2 + 110
Step 3: We consider the new divisor 184 and the new remainder 110, and apply the division lemma to get
184 = 110 x 1 + 74
We consider the new divisor 110 and the new remainder 74,and apply the division lemma to get
110 = 74 x 1 + 36
We consider the new divisor 74 and the new remainder 36,and apply the division lemma to get
74 = 36 x 2 + 2
We consider the new divisor 36 and the new remainder 2,and apply the division lemma to get
36 = 2 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 662 and 478 is 2
Notice that 2 = HCF(36,2) = HCF(74,36) = HCF(110,74) = HCF(184,110) = HCF(478,184) = HCF(662,478) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 849 > 2, we apply the division lemma to 849 and 2, to get
849 = 2 x 424 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 849 is 1
Notice that 1 = HCF(2,1) = HCF(849,2) .
