HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 715, 230 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 781, 715, 230 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 781, 715, 230 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 781, 715, 230 is 1.
HCF(781, 715, 230) = 1
HCF of 781, 715, 230 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 781, 715, 230 is 1.
Highest Common Factor of 781,715,230 is 1
Step 1: Since 781 > 715, we apply the division lemma to 781 and 715, to get
781 = 715 x 1 + 66
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 66 and 715, to get
715 = 66 x 10 + 55
Step 3: We consider the new divisor 66 and the new remainder 55, and apply the division lemma to get
66 = 55 x 1 + 11
We consider the new divisor 55 and the new remainder 11, and apply the division lemma to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 781 and 715 is 11
Notice that 11 = HCF(55,11) = HCF(66,55) = HCF(715,66) = HCF(781,715) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 230 > 11, we apply the division lemma to 230 and 11, to get
230 = 11 x 20 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 230 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(230,11) .
