HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 77980 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 77980 is 10 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 930, 77980 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 930, 77980 is 10.
HCF(930, 77980) = 10
HCF of 930, 77980 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 77980 is 10.
Highest Common Factor of 930,77980 is 10
Step 1: Since 77980 > 930, we apply the division lemma to 77980 and 930, to get
77980 = 930 x 83 + 790
Step 2: Since the reminder 930 ≠ 0, we apply division lemma to 790 and 930, to get
930 = 790 x 1 + 140
Step 3: We consider the new divisor 790 and the new remainder 140, and apply the division lemma to get
790 = 140 x 5 + 90
We consider the new divisor 140 and the new remainder 90,and apply the division lemma to get
140 = 90 x 1 + 50
We consider the new divisor 90 and the new remainder 50,and apply the division lemma to get
90 = 50 x 1 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 930 and 77980 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(90,50) = HCF(140,90) = HCF(790,140) = HCF(930,790) = HCF(77980,930) .
