HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 700 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 700 is 4 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 428, 700 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 428, 700 is 4.
HCF(428, 700) = 4
HCF of 428, 700 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 700 is 4.
Highest Common Factor of 428,700 is 4
Step 1: Since 700 > 428, we apply the division lemma to 700 and 428, to get
700 = 428 x 1 + 272
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 272 and 428, to get
428 = 272 x 1 + 156
Step 3: We consider the new divisor 272 and the new remainder 156, and apply the division lemma to get
272 = 156 x 1 + 116
We consider the new divisor 156 and the new remainder 116,and apply the division lemma to get
156 = 116 x 1 + 40
We consider the new divisor 116 and the new remainder 40,and apply the division lemma to get
116 = 40 x 2 + 36
We consider the new divisor 40 and the new remainder 36,and apply the division lemma to get
40 = 36 x 1 + 4
We consider the new divisor 36 and the new remainder 4,and apply the division lemma to get
36 = 4 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 428 and 700 is 4
Notice that 4 = HCF(36,4) = HCF(40,36) = HCF(116,40) = HCF(156,116) = HCF(272,156) = HCF(428,272) = HCF(700,428) .
