Given numbers are 620, 644, 675, 786
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 644) = 99820
GCD(620, 644) = ( 620 x 644 ) / 99820
= 620 / 644
= 620
Step2:
LCM(4, 675) = 2700
GCD(4, 675) = ( 4 x 675 ) / 2700
= 4 / 675
= 4
Step3:
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
= 1 / 786
= 1
So, Greatest Common Divisor of 620, 644, 675, 786 is 1
