Given numbers are 161, 436, 702, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 436) = 70196
GCD(161, 436) = ( 161 x 436 ) / 70196
= 161 / 436
= 161
Step2:
LCM(1, 702) = 702
GCD(1, 702) = ( 1 x 702 ) / 702
= 1 / 702
= 1
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 161, 436, 702, 158 is 1
