HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 658 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 807, 658 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 807, 658 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 807, 658 is 1.
HCF(807, 658) = 1
HCF of 807, 658 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 807, 658 is 1.
Highest Common Factor of 807,658 is 1
Step 1: Since 807 > 658, we apply the division lemma to 807 and 658, to get
807 = 658 x 1 + 149
Step 2: Since the reminder 658 ≠ 0, we apply division lemma to 149 and 658, to get
658 = 149 x 4 + 62
Step 3: We consider the new divisor 149 and the new remainder 62, and apply the division lemma to get
149 = 62 x 2 + 25
We consider the new divisor 62 and the new remainder 25,and apply the division lemma to get
62 = 25 x 2 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 807 and 658 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(62,25) = HCF(149,62) = HCF(658,149) = HCF(807,658) .
