HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 925, 505, 120 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 925, 505, 120 is 5 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 925, 505, 120 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 925, 505, 120 is 5.
HCF(925, 505, 120) = 5
HCF of 925, 505, 120 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 925, 505, 120 is 5.
Highest Common Factor of 925,505,120 is 5
Step 1: Since 925 > 505, we apply the division lemma to 925 and 505, to get
925 = 505 x 1 + 420
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 420 and 505, to get
505 = 420 x 1 + 85
Step 3: We consider the new divisor 420 and the new remainder 85, and apply the division lemma to get
420 = 85 x 4 + 80
We consider the new divisor 85 and the new remainder 80,and apply the division lemma to get
85 = 80 x 1 + 5
We consider the new divisor 80 and the new remainder 5,and apply the division lemma to get
80 = 5 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 925 and 505 is 5
Notice that 5 = HCF(80,5) = HCF(85,80) = HCF(420,85) = HCF(505,420) = HCF(925,505) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 120 > 5, we apply the division lemma to 120 and 5, to get
120 = 5 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 120 is 5
Notice that 5 = HCF(120,5) .
