HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 744, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 744, 857 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 605, 744, 857 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 605, 744, 857 is 1.
HCF(605, 744, 857) = 1
HCF of 605, 744, 857 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 744, 857 is 1.
Highest Common Factor of 605,744,857 is 1
Step 1: Since 744 > 605, we apply the division lemma to 744 and 605, to get
744 = 605 x 1 + 139
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 139 and 605, to get
605 = 139 x 4 + 49
Step 3: We consider the new divisor 139 and the new remainder 49, and apply the division lemma to get
139 = 49 x 2 + 41
We consider the new divisor 49 and the new remainder 41,and apply the division lemma to get
49 = 41 x 1 + 8
We consider the new divisor 41 and the new remainder 8,and apply the division lemma to get
41 = 8 x 5 + 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 605 and 744 is 1
Notice that 1 = HCF(8,1) = HCF(41,8) = HCF(49,41) = HCF(139,49) = HCF(605,139) = HCF(744,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 857 > 1, we apply the division lemma to 857 and 1, to get
857 = 1 x 857 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 857 is 1
Notice that 1 = HCF(857,1) .
