HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 7090 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 802, 7090 is 2 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 802, 7090 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 802, 7090 is 2.
HCF(802, 7090) = 2
HCF of 802, 7090 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 802, 7090 is 2.
Highest Common Factor of 802,7090 is 2
Step 1: Since 7090 > 802, we apply the division lemma to 7090 and 802, to get
7090 = 802 x 8 + 674
Step 2: Since the reminder 802 ≠ 0, we apply division lemma to 674 and 802, to get
802 = 674 x 1 + 128
Step 3: We consider the new divisor 674 and the new remainder 128, and apply the division lemma to get
674 = 128 x 5 + 34
We consider the new divisor 128 and the new remainder 34,and apply the division lemma to get
128 = 34 x 3 + 26
We consider the new divisor 34 and the new remainder 26,and apply the division lemma to get
34 = 26 x 1 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 802 and 7090 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(34,26) = HCF(128,34) = HCF(674,128) = HCF(802,674) = HCF(7090,802) .
