HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 3980 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 3980 is 20 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, 3980 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, 3980 is 20.
HCF(680, 3980) = 20
HCF of 680, 3980 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, 3980 is 20.
Highest Common Factor of 680,3980 is 20
Step 1: Since 3980 > 680, we apply the division lemma to 3980 and 680, to get
3980 = 680 x 5 + 580
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 580 and 680, to get
680 = 580 x 1 + 100
Step 3: We consider the new divisor 580 and the new remainder 100, and apply the division lemma to get
580 = 100 x 5 + 80
We consider the new divisor 100 and the new remainder 80,and apply the division lemma to get
100 = 80 x 1 + 20
We consider the new divisor 80 and the new remainder 20,and apply the division lemma to get
80 = 20 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 680 and 3980 is 20
Notice that 20 = HCF(80,20) = HCF(100,80) = HCF(580,100) = HCF(680,580) = HCF(3980,680) .
