HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 331, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 331, 639 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 930, 331, 639 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 930, 331, 639 is 1.
HCF(930, 331, 639) = 1
HCF of 930, 331, 639 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 331, 639 is 1.
Highest Common Factor of 930,331,639 is 1
Step 1: Since 930 > 331, we apply the division lemma to 930 and 331, to get
930 = 331 x 2 + 268
Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 268 and 331, to get
331 = 268 x 1 + 63
Step 3: We consider the new divisor 268 and the new remainder 63, and apply the division lemma to get
268 = 63 x 4 + 16
We consider the new divisor 63 and the new remainder 16,and apply the division lemma to get
63 = 16 x 3 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 930 and 331 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(63,16) = HCF(268,63) = HCF(331,268) = HCF(930,331) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get
639 = 1 x 639 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1
Notice that 1 = HCF(639,1) .
