HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 7244, 1715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 7244, 1715 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 658, 7244, 1715 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 658, 7244, 1715 is 1.
HCF(658, 7244, 1715) = 1
HCF of 658, 7244, 1715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 7244, 1715 is 1.
Highest Common Factor of 658,7244,1715 is 1
Step 1: Since 7244 > 658, we apply the division lemma to 7244 and 658, to get
7244 = 658 x 11 + 6
Step 2: Since the reminder 658 ≠ 0, we apply division lemma to 6 and 658, to get
658 = 6 x 109 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 658 and 7244 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(658,6) = HCF(7244,658) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1715 > 2, we apply the division lemma to 1715 and 2, to get
1715 = 2 x 857 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 1715 is 1
Notice that 1 = HCF(2,1) = HCF(1715,2) .
