HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 465, 778, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 465, 778, 191 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 465, 778, 191 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 465, 778, 191 is 1.
HCF(465, 778, 191) = 1
HCF of 465, 778, 191 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 465, 778, 191 is 1.
Highest Common Factor of 465,778,191 is 1
Step 1: Since 778 > 465, we apply the division lemma to 778 and 465, to get
778 = 465 x 1 + 313
Step 2: Since the reminder 465 ≠ 0, we apply division lemma to 313 and 465, to get
465 = 313 x 1 + 152
Step 3: We consider the new divisor 313 and the new remainder 152, and apply the division lemma to get
313 = 152 x 2 + 9
We consider the new divisor 152 and the new remainder 9,and apply the division lemma to get
152 = 9 x 16 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 465 and 778 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(152,9) = HCF(313,152) = HCF(465,313) = HCF(778,465) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get
191 = 1 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1
Notice that 1 = HCF(191,1) .
