HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 7930 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 920, 7930 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 920, 7930 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 920, 7930 is 10.
HCF(920, 7930) = 10
HCF of 920, 7930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 920, 7930 is 10.
Highest Common Factor of 920,7930 is 10
Step 1: Since 7930 > 920, we apply the division lemma to 7930 and 920, to get
7930 = 920 x 8 + 570
Step 2: Since the reminder 920 ≠ 0, we apply division lemma to 570 and 920, to get
920 = 570 x 1 + 350
Step 3: We consider the new divisor 570 and the new remainder 350, and apply the division lemma to get
570 = 350 x 1 + 220
We consider the new divisor 350 and the new remainder 220,and apply the division lemma to get
350 = 220 x 1 + 130
We consider the new divisor 220 and the new remainder 130,and apply the division lemma to get
220 = 130 x 1 + 90
We consider the new divisor 130 and the new remainder 90,and apply the division lemma to get
130 = 90 x 1 + 40
We consider the new divisor 90 and the new remainder 40,and apply the division lemma to get
90 = 40 x 2 + 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 920 and 7930 is 10
Notice that 10 = HCF(40,10) = HCF(90,40) = HCF(130,90) = HCF(220,130) = HCF(350,220) = HCF(570,350) = HCF(920,570) = HCF(7930,920) .
