HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 690 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 690 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 320, 690 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 320, 690 is 10.
HCF(320, 690) = 10
HCF of 320, 690 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 690 is 10.
Highest Common Factor of 320,690 is 10
Step 1: Since 690 > 320, we apply the division lemma to 690 and 320, to get
690 = 320 x 2 + 50
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 50 and 320, to get
320 = 50 x 6 + 20
Step 3: We consider the new divisor 50 and the new remainder 20, and apply the division lemma to get
50 = 20 x 2 + 10
We consider the new divisor 20 and the new remainder 10, and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 320 and 690 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(320,50) = HCF(690,320) .
