HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1955, 7740 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 1955, 7740 is 5 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 1955, 7740 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 1955, 7740 is 5.
HCF(1955, 7740) = 5
HCF of 1955, 7740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1955, 7740 is 5.
Highest Common Factor of 1955,7740 is 5
Step 1: Since 7740 > 1955, we apply the division lemma to 7740 and 1955, to get
7740 = 1955 x 3 + 1875
Step 2: Since the reminder 1955 ≠ 0, we apply division lemma to 1875 and 1955, to get
1955 = 1875 x 1 + 80
Step 3: We consider the new divisor 1875 and the new remainder 80, and apply the division lemma to get
1875 = 80 x 23 + 35
We consider the new divisor 80 and the new remainder 35,and apply the division lemma to get
80 = 35 x 2 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 1955 and 7740 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(80,35) = HCF(1875,80) = HCF(1955,1875) = HCF(7740,1955) .
