HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 890 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 890 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, 890 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, 890 is 1.
HCF(639, 890) = 1
HCF of 639, 890 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, 890 is 1.
Highest Common Factor of 639,890 is 1
Step 1: Since 890 > 639, we apply the division lemma to 890 and 639, to get
890 = 639 x 1 + 251
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 251 and 639, to get
639 = 251 x 2 + 137
Step 3: We consider the new divisor 251 and the new remainder 137, and apply the division lemma to get
251 = 137 x 1 + 114
We consider the new divisor 137 and the new remainder 114,and apply the division lemma to get
137 = 114 x 1 + 23
We consider the new divisor 114 and the new remainder 23,and apply the division lemma to get
114 = 23 x 4 + 22
We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get
23 = 22 x 1 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 890 is 1
Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(114,23) = HCF(137,114) = HCF(251,137) = HCF(639,251) = HCF(890,639) .
