Steps to Calculate GCD of 782, 561, 985, 807 using LCM Formula
Given numbers are 782, 561, 985, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 561) = 25806
GCD(782, 561) = ( 782 x 561 ) / 25806
= 782 / 561
= 782
Step2:
LCM(17, 985) = 16745
GCD(17, 985) = ( 17 x 985 ) / 16745
= 17 / 985
= 17
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 782, 561, 985, 807 is 1
