Given numbers are 565, 155, 132, 639

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(565, 155) = 17515

GCD(565, 155) = ( 565 x 155 ) / 17515

= 565 / 155

= 565

Step2:

LCM(5, 132) = 660

GCD(5, 132) = ( 5 x 132 ) / 660

= 5 / 132

= 5

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 565, 155, 132, 639 is 1
