HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 535, 329 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 535, 329 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 639, 535, 329 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 639, 535, 329 is 1.
HCF(639, 535, 329) = 1
HCF of 639, 535, 329 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 535, 329 is 1.
Highest Common Factor of 639,535,329 is 1
Step 1: Since 639 > 535, we apply the division lemma to 639 and 535, to get
639 = 535 x 1 + 104
Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 104 and 535, to get
535 = 104 x 5 + 15
Step 3: We consider the new divisor 104 and the new remainder 15, and apply the division lemma to get
104 = 15 x 6 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 535 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(104,15) = HCF(535,104) = HCF(639,535) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 329 > 1, we apply the division lemma to 329 and 1, to get
329 = 1 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 329 is 1
Notice that 1 = HCF(329,1) .
