HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 67740 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 67740 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 790, 67740 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 790, 67740 is 10.
HCF(790, 67740) = 10
HCF of 790, 67740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 67740 is 10.
Highest Common Factor of 790,67740 is 10
Step 1: Since 67740 > 790, we apply the division lemma to 67740 and 790, to get
67740 = 790 x 85 + 590
Step 2: Since the reminder 790 ≠ 0, we apply division lemma to 590 and 790, to get
790 = 590 x 1 + 200
Step 3: We consider the new divisor 590 and the new remainder 200, and apply the division lemma to get
590 = 200 x 2 + 190
We consider the new divisor 200 and the new remainder 190,and apply the division lemma to get
200 = 190 x 1 + 10
We consider the new divisor 190 and the new remainder 10,and apply the division lemma to get
190 = 10 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 790 and 67740 is 10
Notice that 10 = HCF(190,10) = HCF(200,190) = HCF(590,200) = HCF(790,590) = HCF(67740,790) .
