Given numbers are 140, 105, 702, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 105) = 420
GCD(140, 105) = ( 140 x 105 ) / 420
= 140 / 105
= 140
Step2:
LCM(35, 702) = 24570
GCD(35, 702) = ( 35 x 702 ) / 24570
= 35 / 702
= 35
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 140, 105, 702, 978 is 1
