HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 358, 781 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 358, 781 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 358, 781 is 1.
HCF(358, 781) = 1
HCF of 358, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 358, 781 is 1.
Highest Common Factor of 358,781 is 1
Step 1: Since 781 > 358, we apply the division lemma to 781 and 358, to get
781 = 358 x 2 + 65
Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 65 and 358, to get
358 = 65 x 5 + 33
Step 3: We consider the new divisor 65 and the new remainder 33, and apply the division lemma to get
65 = 33 x 1 + 32
We consider the new divisor 33 and the new remainder 32,and apply the division lemma to get
33 = 32 x 1 + 1
We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 358 and 781 is 1
Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(65,33) = HCF(358,65) = HCF(781,358) .
