Given numbers are 515, 632, 821, 540
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 632) = 325480
GCD(515, 632) = ( 515 x 632 ) / 325480
= 515 / 632
= 515
Step2:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
Step3:
LCM(1, 540) = 540
GCD(1, 540) = ( 1 x 540 ) / 540
= 1 / 540
= 1
So, Greatest Common Divisor of 515, 632, 821, 540 is 1
