HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 915, 775 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 915, 775 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 525, 915, 775 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 525, 915, 775 is 5.
HCF(525, 915, 775) = 5
HCF of 525, 915, 775 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 915, 775 is 5.
Highest Common Factor of 525,915,775 is 5
Step 1: Since 915 > 525, we apply the division lemma to 915 and 525, to get
915 = 525 x 1 + 390
Step 2: Since the reminder 525 ≠ 0, we apply division lemma to 390 and 525, to get
525 = 390 x 1 + 135
Step 3: We consider the new divisor 390 and the new remainder 135, and apply the division lemma to get
390 = 135 x 2 + 120
We consider the new divisor 135 and the new remainder 120,and apply the division lemma to get
135 = 120 x 1 + 15
We consider the new divisor 120 and the new remainder 15,and apply the division lemma to get
120 = 15 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 525 and 915 is 15
Notice that 15 = HCF(120,15) = HCF(135,120) = HCF(390,135) = HCF(525,390) = HCF(915,525) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 775 > 15, we apply the division lemma to 775 and 15, to get
775 = 15 x 51 + 10
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 10 and 15, to get
15 = 10 x 1 + 5
Step 3: We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 15 and 775 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(775,15) .
