Given numbers are 644, 492, 139, 106

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

Apply this formula for all numbers.

Step1:

LCM(644, 492) = 79212

GCD(644, 492) = ( 644 x 492 ) / 79212

= 644 / 492

= 644

Step2:

LCM(4, 139) = 556

GCD(4, 139) = ( 4 x 139 ) / 556

= 4 / 139

= 4

Step3:

LCM(1, 106) = 106

GCD(1, 106) = ( 1 x 106 ) / 106

= 1 / 106

= 1

So, Greatest Common Divisor of 644, 492, 139, 106 is 1
