HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 886, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 886, 889 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, 886, 889 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, 886, 889 is 1.
HCF(639, 886, 889) = 1
HCF of 639, 886, 889 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, 886, 889 is 1.
Highest Common Factor of 639,886,889 is 1
Step 1: Since 886 > 639, we apply the division lemma to 886 and 639, to get
886 = 639 x 1 + 247
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 247 and 639, to get
639 = 247 x 2 + 145
Step 3: We consider the new divisor 247 and the new remainder 145, and apply the division lemma to get
247 = 145 x 1 + 102
We consider the new divisor 145 and the new remainder 102,and apply the division lemma to get
145 = 102 x 1 + 43
We consider the new divisor 102 and the new remainder 43,and apply the division lemma to get
102 = 43 x 2 + 16
We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get
43 = 16 x 2 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 886 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(102,43) = HCF(145,102) = HCF(247,145) = HCF(639,247) = HCF(886,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 1, we apply the division lemma to 889 and 1, to get
889 = 1 x 889 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 889 is 1
Notice that 1 = HCF(889,1) .
