HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 6139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 6139 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 654, 6139 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 654, 6139 is 1.
HCF(654, 6139) = 1
HCF of 654, 6139 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 6139 is 1.
Highest Common Factor of 654,6139 is 1
Step 1: Since 6139 > 654, we apply the division lemma to 6139 and 654, to get
6139 = 654 x 9 + 253
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 253 and 654, to get
654 = 253 x 2 + 148
Step 3: We consider the new divisor 253 and the new remainder 148, and apply the division lemma to get
253 = 148 x 1 + 105
We consider the new divisor 148 and the new remainder 105,and apply the division lemma to get
148 = 105 x 1 + 43
We consider the new divisor 105 and the new remainder 43,and apply the division lemma to get
105 = 43 x 2 + 19
We consider the new divisor 43 and the new remainder 19,and apply the division lemma to get
43 = 19 x 2 + 5
We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get
19 = 5 x 3 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 654 and 6139 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(43,19) = HCF(105,43) = HCF(148,105) = HCF(253,148) = HCF(654,253) = HCF(6139,654) .
