HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 693, 413 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 693, 413 is 7 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 770, 693, 413 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 770, 693, 413 is 7.
HCF(770, 693, 413) = 7
HCF of 770, 693, 413 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 693, 413 is 7.
Highest Common Factor of 770,693,413 is 7
Step 1: Since 770 > 693, we apply the division lemma to 770 and 693, to get
770 = 693 x 1 + 77
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 77 and 693, to get
693 = 77 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 77, the HCF of 770 and 693 is 77
Notice that 77 = HCF(693,77) = HCF(770,693) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 413 > 77, we apply the division lemma to 413 and 77, to get
413 = 77 x 5 + 28
Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 28 and 77, to get
77 = 28 x 2 + 21
Step 3: We consider the new divisor 28 and the new remainder 21, and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7, and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 77 and 413 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(77,28) = HCF(413,77) .
