HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 615, 622 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 492, 615, 622 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 492, 615, 622 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 492, 615, 622 is 1.
HCF(492, 615, 622) = 1
HCF of 492, 615, 622 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 492, 615, 622 is 1.
Highest Common Factor of 492,615,622 is 1
Step 1: Since 615 > 492, we apply the division lemma to 615 and 492, to get
615 = 492 x 1 + 123
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 123 and 492, to get
492 = 123 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 123, the HCF of 492 and 615 is 123
Notice that 123 = HCF(492,123) = HCF(615,492) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 622 > 123, we apply the division lemma to 622 and 123, to get
622 = 123 x 5 + 7
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 7 and 123, to get
123 = 7 x 17 + 4
Step 3: We consider the new divisor 7 and the new remainder 4, and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 123 and 622 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(123,7) = HCF(622,123) .
