Given numbers are 782, 115, 170, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 115) = 3910
GCD(782, 115) = ( 782 x 115 ) / 3910
= 782 / 115
= 782
Step2:
LCM(23, 170) = 3910
GCD(23, 170) = ( 23 x 170 ) / 3910
= 23 / 170
= 23
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 782, 115, 170, 890 is 1
