HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 695, 865, 824 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 695, 865, 824 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 391, 695, 865, 824 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 391, 695, 865, 824 is 1.
HCF(391, 695, 865, 824) = 1
HCF of 391, 695, 865, 824 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 695, 865, 824 is 1.
Highest Common Factor of 391,695,865,824 is 1
Step 1: Since 695 > 391, we apply the division lemma to 695 and 391, to get
695 = 391 x 1 + 304
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 304 and 391, to get
391 = 304 x 1 + 87
Step 3: We consider the new divisor 304 and the new remainder 87, and apply the division lemma to get
304 = 87 x 3 + 43
We consider the new divisor 87 and the new remainder 43,and apply the division lemma to get
87 = 43 x 2 + 1
We consider the new divisor 43 and the new remainder 1,and apply the division lemma to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 695 is 1
Notice that 1 = HCF(43,1) = HCF(87,43) = HCF(304,87) = HCF(391,304) = HCF(695,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 865 > 1, we apply the division lemma to 865 and 1, to get
865 = 1 x 865 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 865 is 1
Notice that 1 = HCF(865,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 1, we apply the division lemma to 824 and 1, to get
824 = 1 x 824 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 824 is 1
Notice that 1 = HCF(824,1) .
