Given numbers are 155, 414, 655, 411
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 414) = 64170
GCD(155, 414) = ( 155 x 414 ) / 64170
= 155 / 414
= 155
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 411) = 411
GCD(1, 411) = ( 1 x 411 ) / 411
= 1 / 411
= 1
So, Greatest Common Divisor of 155, 414, 655, 411 is 1
