Given numbers are 155, 162, 55
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 162) = 25110
GCD(155, 162) = ( 155 x 162 ) / 25110
= 155 / 162
= 155
Step2:
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
= 1 / 55
= 1
So, Greatest Common Divisor of 155, 162, 55 is 1
