Given numbers are 442, 425, 770, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(442, 425) = 11050
GCD(442, 425) = ( 442 x 425 ) / 11050
= 442 / 425
= 442
Step2:
LCM(17, 770) = 13090
GCD(17, 770) = ( 17 x 770 ) / 13090
= 17 / 770
= 17
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 442, 425, 770, 120 is 1
