HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 900, 505, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 920, 900, 505, 663 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 920, 900, 505, 663 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 920, 900, 505, 663 is 1.
HCF(920, 900, 505, 663) = 1
HCF of 920, 900, 505, 663 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 920, 900, 505, 663 is 1.
Highest Common Factor of 920,900,505,663 is 1
Step 1: Since 920 > 900, we apply the division lemma to 920 and 900, to get
920 = 900 x 1 + 20
Step 2: Since the reminder 900 ≠ 0, we apply division lemma to 20 and 900, to get
900 = 20 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 920 and 900 is 20
Notice that 20 = HCF(900,20) = HCF(920,900) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 20, we apply the division lemma to 505 and 20, to get
505 = 20 x 25 + 5
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 5 and 20, to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 20 and 505 is 5
Notice that 5 = HCF(20,5) = HCF(505,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 663 > 5, we apply the division lemma to 663 and 5, to get
663 = 5 x 132 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 663 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(663,5) .
