HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 611, 749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 611, 749 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 611, 749 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 611, 749 is 1.
HCF(611, 749) = 1
HCF of 611, 749 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 611, 749 is 1.
Highest Common Factor of 611,749 is 1
Step 1: Since 749 > 611, we apply the division lemma to 749 and 611, to get
749 = 611 x 1 + 138
Step 2: Since the reminder 611 ≠ 0, we apply division lemma to 138 and 611, to get
611 = 138 x 4 + 59
Step 3: We consider the new divisor 138 and the new remainder 59, and apply the division lemma to get
138 = 59 x 2 + 20
We consider the new divisor 59 and the new remainder 20,and apply the division lemma to get
59 = 20 x 2 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 611 and 749 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) = HCF(138,59) = HCF(611,138) = HCF(749,611) .
