Given numbers are 702, 705, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(702, 705) = 164970
GCD(702, 705) = ( 702 x 705 ) / 164970
= 702 / 705
= 702
Step2:
LCM(3, 20) = 60
GCD(3, 20) = ( 3 x 20 ) / 60
= 3 / 20
= 3
So, Greatest Common Divisor of 702, 705, 20 is 1
