HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 822, 969, 440 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 822, 969, 440 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 822, 969, 440 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 822, 969, 440 is 1.
HCF(822, 969, 440) = 1
HCF of 822, 969, 440 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 822, 969, 440 is 1.
Highest Common Factor of 822,969,440 is 1
Step 1: Since 969 > 822, we apply the division lemma to 969 and 822, to get
969 = 822 x 1 + 147
Step 2: Since the reminder 822 ≠ 0, we apply division lemma to 147 and 822, to get
822 = 147 x 5 + 87
Step 3: We consider the new divisor 147 and the new remainder 87, and apply the division lemma to get
147 = 87 x 1 + 60
We consider the new divisor 87 and the new remainder 60,and apply the division lemma to get
87 = 60 x 1 + 27
We consider the new divisor 60 and the new remainder 27,and apply the division lemma to get
60 = 27 x 2 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 822 and 969 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(60,27) = HCF(87,60) = HCF(147,87) = HCF(822,147) = HCF(969,822) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 440 > 3, we apply the division lemma to 440 and 3, to get
440 = 3 x 146 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 440 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(440,3) .
