Given numbers are 440, 290, 446, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 290) = 12760
GCD(440, 290) = ( 440 x 290 ) / 12760
= 440 / 290
= 440
Step2:
LCM(10, 446) = 2230
GCD(10, 446) = ( 10 x 446 ) / 2230
= 10 / 446
= 10
Step3:
LCM(2, 770) = 770
GCD(2, 770) = ( 2 x 770 ) / 770
= 2 / 770
= 2
So, Greatest Common Divisor of 440, 290, 446, 770 is 2
