HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 755 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 755 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 980, 755 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 980, 755 is 5.
HCF(980, 755) = 5
HCF of 980, 755 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 755 is 5.
Highest Common Factor of 980,755 is 5
Step 1: Since 980 > 755, we apply the division lemma to 980 and 755, to get
980 = 755 x 1 + 225
Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 225 and 755, to get
755 = 225 x 3 + 80
Step 3: We consider the new divisor 225 and the new remainder 80, and apply the division lemma to get
225 = 80 x 2 + 65
We consider the new divisor 80 and the new remainder 65,and apply the division lemma to get
80 = 65 x 1 + 15
We consider the new divisor 65 and the new remainder 15,and apply the division lemma to get
65 = 15 x 4 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 980 and 755 is 5
Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(80,65) = HCF(225,80) = HCF(755,225) = HCF(980,755) .
