Given numbers are 155, 385, 543, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 385) = 11935
GCD(155, 385) = ( 155 x 385 ) / 11935
= 155 / 385
= 155
Step2:
LCM(5, 543) = 2715
GCD(5, 543) = ( 5 x 543 ) / 2715
= 5 / 543
= 5
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 155, 385, 543, 705 is 1
