Given numbers are 705, 249, 203, 162
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 249) = 58515
GCD(705, 249) = ( 705 x 249 ) / 58515
= 705 / 249
= 705
Step2:
LCM(3, 203) = 609
GCD(3, 203) = ( 3 x 203 ) / 609
= 3 / 203
= 3
Step3:
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
= 1 / 162
= 1
So, Greatest Common Divisor of 705, 249, 203, 162 is 1
