HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 778, 383 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 778, 383 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 485, 778, 383 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 485, 778, 383 is 1.
HCF(485, 778, 383) = 1
HCF of 485, 778, 383 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 778, 383 is 1.
Highest Common Factor of 485,778,383 is 1
Step 1: Since 778 > 485, we apply the division lemma to 778 and 485, to get
778 = 485 x 1 + 293
Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 293 and 485, to get
485 = 293 x 1 + 192
Step 3: We consider the new divisor 293 and the new remainder 192, and apply the division lemma to get
293 = 192 x 1 + 101
We consider the new divisor 192 and the new remainder 101,and apply the division lemma to get
192 = 101 x 1 + 91
We consider the new divisor 101 and the new remainder 91,and apply the division lemma to get
101 = 91 x 1 + 10
We consider the new divisor 91 and the new remainder 10,and apply the division lemma to get
91 = 10 x 9 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 778 is 1
Notice that 1 = HCF(10,1) = HCF(91,10) = HCF(101,91) = HCF(192,101) = HCF(293,192) = HCF(485,293) = HCF(778,485) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 383 > 1, we apply the division lemma to 383 and 1, to get
383 = 1 x 383 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 383 is 1
Notice that 1 = HCF(383,1) .
