Given numbers are 700, 280, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(700, 280) = 1400
GCD(700, 280) = ( 700 x 280 ) / 1400
= 700 / 280
= 700
Step2:
LCM(140, 138) = 9660
GCD(140, 138) = ( 140 x 138 ) / 9660
= 140 / 138
= 140
So, Greatest Common Divisor of 700, 280, 138 is 2
