Given numbers are 142, 831, 828, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 831) = 118002
GCD(142, 831) = ( 142 x 831 ) / 118002
= 142 / 831
= 142
Step2:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
Step3:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
So, Greatest Common Divisor of 142, 831, 828, 581 is 1
