Given numbers are 145, 638, 707, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 638) = 3190
GCD(145, 638) = ( 145 x 638 ) / 3190
= 145 / 638
= 145
Step2:
LCM(29, 707) = 20503
GCD(29, 707) = ( 29 x 707 ) / 20503
= 29 / 707
= 29
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 145, 638, 707, 545 is 1
