HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 703, 893, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 703, 893, 780 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 703, 893, 780 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 703, 893, 780 is 1.
HCF(703, 893, 780) = 1
HCF of 703, 893, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 703, 893, 780 is 1.
Highest Common Factor of 703,893,780 is 1
Step 1: Since 893 > 703, we apply the division lemma to 893 and 703, to get
893 = 703 x 1 + 190
Step 2: Since the reminder 703 ≠ 0, we apply division lemma to 190 and 703, to get
703 = 190 x 3 + 133
Step 3: We consider the new divisor 190 and the new remainder 133, and apply the division lemma to get
190 = 133 x 1 + 57
We consider the new divisor 133 and the new remainder 57,and apply the division lemma to get
133 = 57 x 2 + 19
We consider the new divisor 57 and the new remainder 19,and apply the division lemma to get
57 = 19 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 703 and 893 is 19
Notice that 19 = HCF(57,19) = HCF(133,57) = HCF(190,133) = HCF(703,190) = HCF(893,703) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 19, we apply the division lemma to 780 and 19, to get
780 = 19 x 41 + 1
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 1 and 19, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 780 is 1
Notice that 1 = HCF(19,1) = HCF(780,19) .
