Given numbers are 136, 236, 21, 670

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

Apply this formula for all numbers.

Step1:

LCM(136, 236) = 8024

GCD(136, 236) = ( 136 x 236 ) / 8024

= 136 / 236

= 136

Step2:

LCM(4, 21) = 84

GCD(4, 21) = ( 4 x 21 ) / 84

= 4 / 21

= 4

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 136, 236, 21, 670 is 1
