Given numbers are 855, 708, 423, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 708) = 201780
GCD(855, 708) = ( 855 x 708 ) / 201780
= 855 / 708
= 855
Step2:
LCM(3, 423) = 423
GCD(3, 423) = ( 3 x 423 ) / 423
= 3 / 423
= 3
Step3:
LCM(3, 400) = 1200
GCD(3, 400) = ( 3 x 400 ) / 1200
= 3 / 400
= 3
So, Greatest Common Divisor of 855, 708, 423, 400 is 1
