HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 969, 199 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 969, 199 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 624, 969, 199 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 624, 969, 199 is 1.
HCF(624, 969, 199) = 1
HCF of 624, 969, 199 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 624, 969, 199 is 1.
Highest Common Factor of 624,969,199 is 1
Step 1: Since 969 > 624, we apply the division lemma to 969 and 624, to get
969 = 624 x 1 + 345
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 345 and 624, to get
624 = 345 x 1 + 279
Step 3: We consider the new divisor 345 and the new remainder 279, and apply the division lemma to get
345 = 279 x 1 + 66
We consider the new divisor 279 and the new remainder 66,and apply the division lemma to get
279 = 66 x 4 + 15
We consider the new divisor 66 and the new remainder 15,and apply the division lemma to get
66 = 15 x 4 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 624 and 969 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(66,15) = HCF(279,66) = HCF(345,279) = HCF(624,345) = HCF(969,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 199 > 3, we apply the division lemma to 199 and 3, to get
199 = 3 x 66 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 199 is 1
Notice that 1 = HCF(3,1) = HCF(199,3) .
