Given numbers are 840, 763, 639, 546
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 763) = 91560
GCD(840, 763) = ( 840 x 763 ) / 91560
= 840 / 763
= 840
Step2:
LCM(7, 639) = 4473
GCD(7, 639) = ( 7 x 639 ) / 4473
= 7 / 639
= 7
Step3:
LCM(1, 546) = 546
GCD(1, 546) = ( 1 x 546 ) / 546
= 1 / 546
= 1
So, Greatest Common Divisor of 840, 763, 639, 546 is 1
