Given numbers are 690, 140, 886, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 140) = 9660
GCD(690, 140) = ( 690 x 140 ) / 9660
= 690 / 140
= 690
Step2:
LCM(10, 886) = 4430
GCD(10, 886) = ( 10 x 886 ) / 4430
= 10 / 886
= 10
Step3:
LCM(2, 305) = 610
GCD(2, 305) = ( 2 x 305 ) / 610
= 2 / 305
= 2
So, Greatest Common Divisor of 690, 140, 886, 305 is 1
