Given numbers are 465, 642, 510, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(465, 642) = 99510
GCD(465, 642) = ( 465 x 642 ) / 99510
= 465 / 642
= 465
Step2:
LCM(3, 510) = 510
GCD(3, 510) = ( 3 x 510 ) / 510
= 3 / 510
= 3
Step3:
LCM(3, 643) = 1929
GCD(3, 643) = ( 3 x 643 ) / 1929
= 3 / 643
= 3
So, Greatest Common Divisor of 465, 642, 510, 643 is 1
