Steps to Calculate GCD of 217, 511, 844, 782 using LCM Formula
Given numbers are 217, 511, 844, 782
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 511) = 15841
GCD(217, 511) = ( 217 x 511 ) / 15841
= 217 / 511
= 217
Step2:
LCM(7, 844) = 5908
GCD(7, 844) = ( 7 x 844 ) / 5908
= 7 / 844
= 7
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 217, 511, 844, 782 is 1
