HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 626, 970 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 626, 970 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 870, 626, 970 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 870, 626, 970 is 2.
HCF(870, 626, 970) = 2
HCF of 870, 626, 970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 626, 970 is 2.
Highest Common Factor of 870,626,970 is 2
Step 1: Since 870 > 626, we apply the division lemma to 870 and 626, to get
870 = 626 x 1 + 244
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 244 and 626, to get
626 = 244 x 2 + 138
Step 3: We consider the new divisor 244 and the new remainder 138, and apply the division lemma to get
244 = 138 x 1 + 106
We consider the new divisor 138 and the new remainder 106,and apply the division lemma to get
138 = 106 x 1 + 32
We consider the new divisor 106 and the new remainder 32,and apply the division lemma to get
106 = 32 x 3 + 10
We consider the new divisor 32 and the new remainder 10,and apply the division lemma to get
32 = 10 x 3 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 870 and 626 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) = HCF(106,32) = HCF(138,106) = HCF(244,138) = HCF(626,244) = HCF(870,626) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 970 > 2, we apply the division lemma to 970 and 2, to get
970 = 2 x 485 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 970 is 2
Notice that 2 = HCF(970,2) .
