HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 570, 936 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 570, 936 is 1 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 665, 570, 936 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 665, 570, 936 is 1.
HCF(665, 570, 936) = 1
HCF of 665, 570, 936 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 570, 936 is 1.
Highest Common Factor of 665,570,936 is 1
Step 1: Since 665 > 570, we apply the division lemma to 665 and 570, to get
665 = 570 x 1 + 95
Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 95 and 570, to get
570 = 95 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 95, the HCF of 665 and 570 is 95
Notice that 95 = HCF(570,95) = HCF(665,570) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 936 > 95, we apply the division lemma to 936 and 95, to get
936 = 95 x 9 + 81
Step 2: Since the reminder 95 ≠ 0, we apply division lemma to 81 and 95, to get
95 = 81 x 1 + 14
Step 3: We consider the new divisor 81 and the new remainder 14, and apply the division lemma to get
81 = 14 x 5 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 95 and 936 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(81,14) = HCF(95,81) = HCF(936,95) .
