HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 359, 863, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 359, 863, 78 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 359, 863, 78 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 359, 863, 78 is 1.
HCF(359, 863, 78) = 1
HCF of 359, 863, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 359, 863, 78 is 1.
Highest Common Factor of 359,863,78 is 1
Step 1: Since 863 > 359, we apply the division lemma to 863 and 359, to get
863 = 359 x 2 + 145
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 145 and 359, to get
359 = 145 x 2 + 69
Step 3: We consider the new divisor 145 and the new remainder 69, and apply the division lemma to get
145 = 69 x 2 + 7
We consider the new divisor 69 and the new remainder 7,and apply the division lemma to get
69 = 7 x 9 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 359 and 863 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(69,7) = HCF(145,69) = HCF(359,145) = HCF(863,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
