GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 555) = 17205
GCD(155, 555) = ( 155 x 555 ) / 17205
= 155 / 555
= 155
Step2:
LCM(5, 805) = 805
GCD(5, 805) = ( 5 x 805 ) / 805
= 5 / 805
= 5
Step3:
LCM(5, 834) = 4170
GCD(5, 834) = ( 5 x 834 ) / 4170
= 5 / 834
= 5
So, Greatest Common Divisor of 155, 555, 805, 834 is 1
