HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 520, 841 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 520, 841 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 680, 520, 841 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 680, 520, 841 is 1.
HCF(680, 520, 841) = 1
HCF of 680, 520, 841 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 520, 841 is 1.
Highest Common Factor of 680,520,841 is 1
Step 1: Since 680 > 520, we apply the division lemma to 680 and 520, to get
680 = 520 x 1 + 160
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 160 and 520, to get
520 = 160 x 3 + 40
Step 3: We consider the new divisor 160 and the new remainder 40, and apply the division lemma to get
160 = 40 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 680 and 520 is 40
Notice that 40 = HCF(160,40) = HCF(520,160) = HCF(680,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 841 > 40, we apply the division lemma to 841 and 40, to get
841 = 40 x 21 + 1
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 1 and 40, to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 40 and 841 is 1
Notice that 1 = HCF(40,1) = HCF(841,40) .
