HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7780, 1043 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7780, 1043 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 7780, 1043 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 7780, 1043 is 1.
HCF(7780, 1043) = 1
HCF of 7780, 1043 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7780, 1043 is 1.
Highest Common Factor of 7780,1043 is 1
Step 1: Since 7780 > 1043, we apply the division lemma to 7780 and 1043, to get
7780 = 1043 x 7 + 479
Step 2: Since the reminder 1043 ≠ 0, we apply division lemma to 479 and 1043, to get
1043 = 479 x 2 + 85
Step 3: We consider the new divisor 479 and the new remainder 85, and apply the division lemma to get
479 = 85 x 5 + 54
We consider the new divisor 85 and the new remainder 54,and apply the division lemma to get
85 = 54 x 1 + 31
We consider the new divisor 54 and the new remainder 31,and apply the division lemma to get
54 = 31 x 1 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7780 and 1043 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(54,31) = HCF(85,54) = HCF(479,85) = HCF(1043,479) = HCF(7780,1043) .
