HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 734, 386, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 734, 386, 685 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 734, 386, 685 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 734, 386, 685 is 1.
HCF(734, 386, 685) = 1
HCF of 734, 386, 685 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 734, 386, 685 is 1.
Highest Common Factor of 734,386,685 is 1
Step 1: Since 734 > 386, we apply the division lemma to 734 and 386, to get
734 = 386 x 1 + 348
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 348 and 386, to get
386 = 348 x 1 + 38
Step 3: We consider the new divisor 348 and the new remainder 38, and apply the division lemma to get
348 = 38 x 9 + 6
We consider the new divisor 38 and the new remainder 6,and apply the division lemma to get
38 = 6 x 6 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 734 and 386 is 2
Notice that 2 = HCF(6,2) = HCF(38,6) = HCF(348,38) = HCF(386,348) = HCF(734,386) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 685 > 2, we apply the division lemma to 685 and 2, to get
685 = 2 x 342 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 685 is 1
Notice that 1 = HCF(2,1) = HCF(685,2) .
