Given numbers are 138, 501, 539, 749
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 501) = 23046
GCD(138, 501) = ( 138 x 501 ) / 23046
= 138 / 501
= 138
Step2:
LCM(3, 539) = 1617
GCD(3, 539) = ( 3 x 539 ) / 1617
= 3 / 539
= 3
Step3:
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
= 1 / 749
= 1
So, Greatest Common Divisor of 138, 501, 539, 749 is 1
