Given numbers are 758, 390, 828, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(758, 390) = 147810
GCD(758, 390) = ( 758 x 390 ) / 147810
= 758 / 390
= 758
Step2:
LCM(2, 828) = 828
GCD(2, 828) = ( 2 x 828 ) / 828
= 2 / 828
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 758, 390, 828, 805 is 1
