HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 871, 649 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 871, 649 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 479, 871, 649 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 479, 871, 649 is 1.
HCF(479, 871, 649) = 1
HCF of 479, 871, 649 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 871, 649 is 1.
Highest Common Factor of 479,871,649 is 1
Step 1: Since 871 > 479, we apply the division lemma to 871 and 479, to get
871 = 479 x 1 + 392
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 392 and 479, to get
479 = 392 x 1 + 87
Step 3: We consider the new divisor 392 and the new remainder 87, and apply the division lemma to get
392 = 87 x 4 + 44
We consider the new divisor 87 and the new remainder 44,and apply the division lemma to get
87 = 44 x 1 + 43
We consider the new divisor 44 and the new remainder 43,and apply the division lemma to get
44 = 43 x 1 + 1
We consider the new divisor 43 and the new remainder 1,and apply the division lemma to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 871 is 1
Notice that 1 = HCF(43,1) = HCF(44,43) = HCF(87,44) = HCF(392,87) = HCF(479,392) = HCF(871,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 1, we apply the division lemma to 649 and 1, to get
649 = 1 x 649 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 649 is 1
Notice that 1 = HCF(649,1) .
