GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 624) = 66768
GCD(642, 624) = ( 642 x 624 ) / 66768
= 642 / 624
= 642
Step2:
LCM(6, 992) = 2976
GCD(6, 992) = ( 6 x 992 ) / 2976
= 6 / 992
= 6
Step3:
LCM(2, 545) = 1090
GCD(2, 545) = ( 2 x 545 ) / 1090
= 2 / 545
= 2
So, Greatest Common Divisor of 642, 624, 992, 545 is 1
