GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(528, 642) = 56496
GCD(528, 642) = ( 528 x 642 ) / 56496
= 528 / 642
= 528
Step2:
LCM(6, 255) = 510
GCD(6, 255) = ( 6 x 255 ) / 510
= 6 / 255
= 6
Step3:
LCM(3, 440) = 1320
GCD(3, 440) = ( 3 x 440 ) / 1320
= 3 / 440
= 3
So, Greatest Common Divisor of 528, 642, 255, 440 is 1
