Given numbers are 153, 687, 85, 540
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 687) = 35037
GCD(153, 687) = ( 153 x 687 ) / 35037
= 153 / 687
= 153
Step2:
LCM(3, 85) = 255
GCD(3, 85) = ( 3 x 85 ) / 255
= 3 / 85
= 3
Step3:
LCM(1, 540) = 540
GCD(1, 540) = ( 1 x 540 ) / 540
= 1 / 540
= 1
So, Greatest Common Divisor of 153, 687, 85, 540 is 1
