Given numbers are 786, 444, 545, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 444) = 58164
GCD(786, 444) = ( 786 x 444 ) / 58164
= 786 / 444
= 786
Step2:
LCM(6, 545) = 3270
GCD(6, 545) = ( 6 x 545 ) / 3270
= 6 / 545
= 6
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 786, 444, 545, 398 is 1
