Given numbers are 650, 340, 685, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 340) = 22100
GCD(650, 340) = ( 650 x 340 ) / 22100
= 650 / 340
= 650
Step2:
LCM(10, 685) = 1370
GCD(10, 685) = ( 10 x 685 ) / 1370
= 10 / 685
= 10
Step3:
LCM(5, 455) = 455
GCD(5, 455) = ( 5 x 455 ) / 455
= 5 / 455
= 5
So, Greatest Common Divisor of 650, 340, 685, 455 is 5
