HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 779, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 779, 455 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 868, 779, 455 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 868, 779, 455 is 1.
HCF(868, 779, 455) = 1
HCF of 868, 779, 455 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 779, 455 is 1.
Highest Common Factor of 868,779,455 is 1
Step 1: Since 868 > 779, we apply the division lemma to 868 and 779, to get
868 = 779 x 1 + 89
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 89 and 779, to get
779 = 89 x 8 + 67
Step 3: We consider the new divisor 89 and the new remainder 67, and apply the division lemma to get
89 = 67 x 1 + 22
We consider the new divisor 67 and the new remainder 22,and apply the division lemma to get
67 = 22 x 3 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 868 and 779 is 1
Notice that 1 = HCF(22,1) = HCF(67,22) = HCF(89,67) = HCF(779,89) = HCF(868,779) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get
455 = 1 x 455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1
Notice that 1 = HCF(455,1) .
